In the scene where Lori wakes up in the police station and follows the dropping blood, she turns a corner because she hears a little crying. Right after she turns the corner, the cameras show office windows. You can see someone sitting down and a cameraman on his knees. [I just watched this scene 5 times in a row and there is absolutely no cameraman or person other than the little girl]

In "Jason Goes to Hell", it is stated that all the cabins at Camp Crystal Lake were torn down. Yet in this movie we see many of them, and Freddy and Jason even fight in one. [This movie ignores some of the earlier movies. Therefore they can add anything to this movie they want.]

In the corn scene, Jason is set on fire, and then takes out his machete and the sheath is still on, but then its gone after the machete is thrown into the air. [After Jason pulls out his machete, there are several shots where he is not shown and the camera is on the kid he is chasing. He had plenty of time and opportunity to remove the sheath.]

When the kid wakes up and his father is sitting beside him with his neck chopped on the porch of his house, the kid hears a noise in the bushes. As he walks towards them, we get a shot of the bushes moving - if you look to the right of the bushes, the shadow of someone shaking them is visible. [First of all, Blake hears the noise in the bushes in his dream, before he wakes up to find his father dead. Secondly, why shouldn't there be a shadow? There is actually someone there, namely Freddy. It's a bit sloppy of him to expose even as much as a shadow, but it is possible, espescially seeing how eager and concentrated he is on scaring and killing Blake.]

In the scene where Linderman, Kia, Will, Detective Stubbs, and Freeburg are sitting at a table discussing how to destory Freddy and Jason, there is a Sprite bottle on the table. The cap to the bottle is seen right next to it, but as the shots change angles, the cap is about 6 inches away from the bottle, and then back to being right next to it again. [This never happens. Even so, there are several shots not showing Will and the Sprite bottle at all. He could have had several sips from the bottle placing it close/near the cap without us noticing it at all.]

In the final fight, when Freddy is knocked off the construction site and is hanging by his foot, in one shot his hat has fallen off his head, but when the camera changes back to him when hes swinging his hat is back on his head. [His hat never reappears on his head, while he's hanging there.]

If you watch the final battle on the dock (I think it happens other times in the movie) Freddy's shirt comes up over his back revealing no burns. It's stated many times in all the Nightmare on Elm Street films (and this one) that Freddy's entire body was burned badly. [I watched it over and over, but Freddy's shirt never flies up revealing no burns.]

This is the first movie where Jason speaks. Just after he throws the table and walks towards Freddy, you can hear Jason whisper the word "die" at least four times as he walks. [After a close listen, I think that you will find that it is part of the song that is just about to play.]

After Freddy shoots the gas tanks at Jason, there's a shot of Jason flying through the air, landing and getting up. The next shot is of Freddy on top of the scaffolds where he says, "Hey A**hole. Up here." Now there's no way Freddy could have gotten from behind where the gas tanks were to the top of the scaffolds in that short a time. And he's in the real world so he doesn't have all of his special abilities. [In the real world, Freddy does in fact still have some powers. As already shown, he can withstand a lot of pain and as proven in "Freddy's Dead", he can defy gravity and climb up walls. Who's to say he can't run faster than a mortal?]

Mark is trapped in his dream and at the window yelling for help, then he is slashed across the face by an invisible Freddy. Will and Lori look across the room, and in the mirror they see the reflection of "Freddy's Back" burned into a dead Mark's skin. Freddy would have had to have written the words backwards, in order for them to see it correctly. [Well Freddy knew they would see it in the mirror and then wrote in a way so they can see it in the mirror.]

When the guy from the party at the start wakes up and finds his dad sitting next to him, he taps his shoulder and his head jumps right off where Jason has cut it. There's no way it would jump up, it would just tip forwards. [It does not jump up in the air. Blake tapped his father's head and it fell sideways into Blake's arms.]

In the big fight scene on the pier, Freddy stabs Jason in the eyes with his knives, then Freddy goes to punch Jason and he sees it to block it with his arm. Surely he'd have been blinded from this point on in the film? [Freddy only stabbed him once, so his eye may have been sliced, but it was not removed. With his regenerative abilities, his eye was still pretty much in place for the rest of the fight.]

During the first fight scene between Freddy and Jason in the dream world, Jason tosses Freddy into some pipes which causes water to spray everywhere. When Jason is about to attack Freddy and stops to back away from the water, it is explained that Jason is "afraid" of the water. While logical on paper, this makes absolutely no sense with the rest of the Friday the 13th movies and an earlier scene in Freddy vs. Jason. Jason has on many occasions ventured freely into Crystal Lake to kill his victims in earlier movies, and in this movie he walks all the way to Elm Street in the pouring rain. Surely if he was afraid of water he'd not have completely submerged himself in a lake, and would have taken shelter under a tree until the rain storm passed. [Jason is only afraid of water when it poses a threat to him, such as when he is drowning.]

When Will and Lori get out of the Lake at the end, Lori's arm isn't burned. It's only scratched. [Lori's arm wasn't in the fire long. It most likely didn't have much effect on her.]

Numerous times throughout the film Jason is shown as missing his right eye and possessing his left eye. This does not fit with the other "Friday the 13th" films. In Part IV "The Final Chapter" Tommy hits the left side of Jason's head with a machete, destroying Jason's left eye in the process. In later films, namely Part VI and Part VII Jason has his right eye and is missing his left eye. Somehow this was reversed in Freddy Vs. Jason. [That is true. But we are supposed to guess that Jason regenerates his eye and then is hit in the other eye. Its a very confusing thing.]

In one of the first scenes the two boys arrive at Lori's house, and while it's raining cats and dogs outside and one of them says "I'm soaking wet", their coats and other clothing are perfectly dry, as well as the sixpack of beer they're carying. [Both Trey and Blake are both wet. Their clothes and hair, all wet.]

Lori wouldn't have been able to climb out of the water or help Will up with her very burned arm without causing herself a lot of pain, yet she shows no sign of any pain. [It's possible that the fire didnt have much effect on her. Her arm wasn't in the fire for that long.]

When Jason throws Linderman against the wall, the metal spike that stabs him isn't there. But it is there (obviously) when he gets stabbed by it. It's also not there when Jason is in that corner about to drag Freddy through the windows. [If you look, you do see a shelf bracket sticking out.]

In the scene where Jason comes out of the cornfield and starts killing the ravers, he kills a boy with a hat on by slashing through his chest. A few shots later you see Jason killing the same boy again from a different angle. [Actually, it is two different ravers in similar shirts with the same horizontal slash. Notice that one is wearing a beanie while the other is wearing a bucket hat - this shows they are different people.]

In the institute, Will's friend gets out of his room to get the guards keys. He couldn't have gotten out of his room because there isn't a handle or door lock inside the room. [Yes, Will's friend gets out of his room to get the guards' keys; but the guards opened his door to give him the shot. ]
