Amazing-best movie from all 3 you have to agree though if you read the book there are millions of flaws-like in the movie.
1) It is not mentions who are mooney (Proffesor Lupin-werewolf), wormtail (Peter pettigrew-rat), padfoot (Sirius-dog) and prongs(James Potter-stag). And why were they called so (Coz of the animals they could turn into).
2) Or why Harrys patronus is always stag (Coz his father was a animagus guess which animal he turned into?)
3) Or what does the divination teachers prediction mean.(What it says and it comes true).
4) Also harry does not see peter pettigrew in the map....Lupin does after he confiscates it!
5) Also siriuss sigh for permission to go to hogsmeade village for harry does not arrive thus ron does not get a new owl(the new owl is from sirius coz ron loses his rat thats who peter pettigrew is).
6) The broomstick arrives on christmas with harrys presents not when he receives it in the movie.
7) Hermoine slaps malfoy not punches him{though this is a pro:)}.
8) When the 3 go to hagrids hut hagrid does not give scabbers to ron-hermoine finds scabbers in a milk jug.
9) And when snape is taking defense against the dark arts class harry arrives late he is not in class when snape arrives in class.
10) Also The divination teacher makes her prediction during the final exams not after the lesson hermoine leaves the class
11) And harry stays in the leaky cloudron in the begining for 2 weeks not one day
12) Snape does not catch harry with the map in the corridor but rather when in hogsmead under the invisibility cloak when harry is hitting malfoy his invisibility cloak slips of his head.So malfoy tells this to snape and therefore snape calls harry to his office and asks him to empty his pockets and then lupin comes and covers up for harry though he knows harry has been to hogsmead and thats why and when he scolds harry bout repaying his parents scarafice.
Ok Im getting boring but I have many more differences so you see why you should read the book. Though if u read reviews of people like me you wont need to do that. But the new movie was the best from the lot. The new director is a good change. Read here for updates on my review.
