Harry Potter and the Prisoner of Azkaban is an epic failure of a movie because they did such a poor job of book to movie translation. Some very critical plot points are left out,resulting in a very unfulfilling movie. This movie completely misses the boat by failing to include plot points such as why the marauders became animagi in the 1st place,the history of the map,and,most importantly,what motivated Sirius to escape from Azkaban. As Sirius escape from Azkaban sets in motion the events of the book that set in motion the rest of the series,to not explain to movie audience exactly what motivated Sirius to escape from Azkaban was an epic plot failure. Although there are some great aspects to this movie,the fact they did such a bad job with the plot makes an epic failure. Alfonso talks on the DVD extras about "exploring emotional territories." And that's exactly what went wrong with this movie. Alfonso was more interested in "emotional territories" than in plot and this movie suffers for it. This movie is 19 minutes shorter than the 5 star classic Harry Potter and the Chamber of Secrets,so you can't say they didn't have time to explain these things. I will admit,the Knight Bus scene was fun and Buckbeak is breathtaking. And Hermione's punch was awesome. And the time turner scene was quite well done. But,when the plot fails,the movie fails. Epic Fail. i do not recommend this movie. However,in terms of who it's okay for,it's not much worse than Chamber of Secrets. The werewolf and the big dog are probably equal to the giant talking spider and the basilisk. The only thing that would make Azkaban somewhat worse than Chamber would be the dementors. Because of the creepiness of the dementors,though,this is off for preschoolers and kindergarteners. It's pause for kids in grades 1-2. It's on for kids in 3rd grade and older.
