In the scene where Daniel gets beat up at the dojo, Daniel escapes and Mike follows him to bring him back. When Mike gets thrown through the doors by Miyagi, you can see the bench he jumped from before it gets pulled from view. [I just got done watching this movie. After watching this scene 5 times, I could not see and bench being pulled out of the way or that he could have jumped from anywhere in the scene.]

In the first minute of the film, Daniel is seen walking into the King Cobra Dojo alone, and is wearing a red Blazer. The sensei then asks what the problem is with Johnny, and looks over at Daniel. In the next shot, Mr. Miyagi has appeared, and Daniel is wearing a flannelette shirt, and has new grazes on his head and a bandaid. [What you're seeing is a flashback of two separate events from the first film. When he was wearing the red blazer, he was checking out the dojo just before joining his mom for dinner. When he was wearing the flannel shirt, it was the day after the Halloween dance, when he and Miyagi went there together to issue their challenge for the tournament.]

Even though the karate tournament again is for participants under 18, Daniel appears to be in his late 20's and Mike Barnes is at least 25. [Just because Daniel looks older than 20 does not mean to say that his character actually is. It is not a mistake for someone to look older than the character they are playing, as it is common for actors to play characters much younger than themselves.]

When Mike is beating up Daniel in the Bonsai store, Miyagi shows up and Mike says something like "Take him", then shouts or points for Dennis. Dennis approaches Miyagi, but in the following shot it is actually Mike fighting Miyagi instead of Dennis. [Mike shouts "nail him" and it was Snake who goes after Mr. Miyagi and gets beat up. Mike then goes after Mr. Miyagi and gets kicked in the butt and out the door. Dennis never goes after Mr. Miyagi.]

After Daniel finally signed the application at the bottom of the cliff, he tells Barnes and his two buddies to pull him and Jessica back up. If Daniel and Jessica needed to depend entirely on somebody at the top in order to come back up, why did those two dummies both descend by themselves? [When Daniel and Jessica went down the cliff, it was with the intention of climbing back up at a slow, careful pace. However, because of the delay they got from Barnes & co., they risk getting caught in the flash flood and therefore need help getting up fast.]

Jessica is with Daniel when Silver tells him that tournament guys are suckers for the front sweep. However, later in the movie at the Bonsai shop, Daniel decides that he will tell her the exact same thing as if she's never met Silver nor was ever there when he told Daniel. She also seems very surprised and excited when Daniel tells her. [Maybe Daniel was overly excited about the front sweeps that he forgot Jessica was with him when he told her. She also doesn't seem that surprised. She looks at him like she already knew but was going along with what he was saying just to be nice.]

By the time we see Daniel in Karate Kid III, Daniel has gained a lot of experience in karate. In Part I, Daniel won the championship for the All Valley Tournament, which supposedly means that he knows karate best in the Los Angeles area. In Part II, Daniel defeats Chozen in a fight to the death, and Chozen is a real karate master (as is evident when he beats up his students in Part II). With all this experience in karate, why is Daniel so easily beaten up by Mike and his friends? With all he's learned, he should be able to defeat them easily. (With Mr. Silver and Kreese, that's understandable since they are very experienced as well.). [It is pointed out by one of the trio of bad guys that the techniques he uses will not work against Barnes; they even make fun of the move he used to win in the first movie. So he is easily beaten because they have come up with different moves, and counters to his moves, so he will have to learn new techniques.]

Why is Daniel risking his life to get the bonsai tree to sell to help the shop when he has that shiny yellow classic car? He can easily sell that for enough to help out. Then when he brings the broken tree to the shop Mr. Miyagi says he sold his truck to pay for them. Later at Mr. Miyagi's house, in the background are Daniel's car and two other classics easily worth more money then Miyagi's old truck. [The classic cars are practically irreplaceable and they would hate to lose them, while they don't really care that much about the bonsai or the old truck.]

The tournament that Daniel is in is the All Valley under 18 tournament, but we already know that he has graduated from high school and was about to attend college. [His birthday could be in the summer and, therefore, he could still be 17 years old and have graduated high school.]
