Story Summary: Harry Potter is having a tough time with his relatives (yet again). He runs away after using magic to inflate Uncle Vernon's sister Marge who was being offensive towards Harry's parents. Initially scared for using magic outside the school, he is pleasantly surprised that he won't be penalized after all. However, he soon learns that a dangerous criminal and Voldemort's trusted aide Sirius Black has escaped from the Azkaban prison and wants to kill Harry to avenge the Dark Lord. To worsen the conditions for Harry, vile shape-shifters called Dementors are appointed to guard the school gates and inexplicably happen to have the most horrible effect on him. Little does Harry know that by the end of this year, many holes in his past (whatever he knows of it) will be filled up and he will have a clearer vision of what the future has in store...
It's better than the movie in all the aspects. More info on the story, better scenes at Hogwarts and Hogsmead. In every aspect if really wanna know the Prisoner of Azkaban well you need to read the book. You get better look to old and new characters.
Ermm..nowhere? Alfonso Cauron did a really bad job with it. The world loses its magic. You barely see the trio wearing the wizards robes, parts of the story were changed. The scenes change in a weird and really fast way. It might be better explained the whole thing with the time travel though. But that's all for me. Worst Harry Potter movie XD
