Plot hole: 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 is in December, so he must already be 18.

Question: I've heard that many people (Ralph Macchio included) do not like this movie. Is there a reason why?
Answer: This is just a theory, but in addition to a bunch of people thinking it was too much like the first movie, I think another reason was the lack of love scenes. The girl Daniel liked in the movie had a boyfriend, so their relationship was just one of friendship, whereas in the first two movies there was quite a bit of love in Daniel's life, starting with the girl who went to school with him and was Johnny's ex, and then came his Japanese love in the second movie.
The real reason there was just a friendship with the girl in this film was because Robyn Lively was only 16 and Ralph Macchio (who was in his late 20s) felt it wasn't appropriate to date someone that young, so they wrote the story that way.
Answer: Ralph Macchio admitted that he didn't like it as he felt that they were just making the first movie all over again and left out a lot of good stuff.
