Why are there three games in the movie Harry Potter and the Goblet of Fire? Why is Harry the only one fighting against the dragon?

In fact, whether reading a book or watching a movie, I feel the same, and I feel very uncomfortable! ! but ...

I saw a few people upstairs, and I thought what I said was quite reasonable, so I summarized it, hoping it would be clear after reading it.

1. Because the process of shooting a special effect is very complicated, plus editing and the like, it takes a long time and costs a lot.

In the play, Harry is the protagonist. When other players play dragons, the focus is on the story of Harry and Hermione and the reporter in the tent. At the same time, the dragon fighting process of other players is over. ...

3. Write a book in detail. If you write every plot in detail, it will become frivolous. So this part of the story book is not mentioned, and there is no need to reinvent the wheel in the movie.

Hope I can be satisfied! ! ! !
