The Sixth one was dire. Not only did it deviate from the book, but it made core plot line changes and core character changes which just annoyed me. I cringed through most of the 6th film not because it wasn't a close resemblance to the book but because it was absolute bull in some parts, such as the Burrow burning down, Ginny running around Harry like a puppy and Harry just standing around watching as Dumbledore is killed instead of being restrained from saving him.
Also some of the casting is just poor. Snape is amazing in his part though.
For those reasons, I'm probably not going to watch it. I hope sometime in the future these are all remade. Maybe not the first one, but the rest were shockingly bad.
