I feel that some of this could have been alleviated if there was a little more time to flesh out and stress the emotions behind characters' actions. I think the filmmakers did the right thing in making this one film instead of two. However, I think they did punk out by holding on to the idea of "time constraints." Given that this film is the series' transition into darker, slightly more mature territory, why not go all the way and make the running time grown up too? Audiences ate up the three-hour-long Lord Of The Rings films at theaters (and the even longer versions on DVD) and I think they would probably support a three-hour Harry Potter film. There is more than enough story in the later Harry Potter books to keep things interesting for that length of time.
Overall, Harry Potter And The Goblet Of Fire is a solid entry in the film series. The acting, action, and special effects are good throughout and overshadow the issues of adapting such a long book to the big screen. I just hope that the filmmakers behind the next film take the necessary risks and make sure that the series' streak of quality films continues into the future.
