How are they supposed to lead into the next one?

Rating: Null/10 (5 June 2004)

Please tell me this because they left a whole lot out. First of all, they didn't explain ANYTHING. They didn't explain that Lupin, Black, Potter, and Pettigrew were all best friends and classmates. They didn't explain that Sirius, James, and Peter became unregistered animagi to help Remus in his werewolf state. They didn't explain about the map. They didn't put in anything about Harry's parents which was all through the book as the dementors appeared. The fact that Harry spent a lot of time working on his Patronus was a big part of the book too. They left out the part about Harry seeing the Firebolt and getting it before he did in the movie....not to mention the fact that Hermione told Professor McGonagall and she took it away because she thought it may be cursed. That being only a few things that they left out. Needless to say I'm not pleased with this movie at all.
I won't be going to see the others if they're made in this way.
