The number of grief I have to Cuaron's movie are endless. I could speak about the characters being completely ootc, the fact that apparently shooting a movie with a grey filter makes it "dark" (sorry no) or that the acting was just all in all frankly terrible (you can argue that it always was but this one has some scenes that just takes the cake to me, I still don't get how a director can let this happen).

More or so I can, when I'm in a very good mood, do understand that POA is the easiest movie to like when you're not a compelling readers of the books but that's where I just basically rage.

POA was just a filmmaker more concerned with looking cool than staying faithful to the books. That's how I took the all thing. It has the name Harry Potter on it but that's pretty much it. I don't even find the movie that beautiful or anything. Just grey. It never touched me. At all. I felt disconnected. Worse, I felt it like a joke. Like Cuaron could tell everyone "hey look I did an HP movie lol". Cool bro.

Colombus movies were not particularly grandiose. They were just the paper translated on screen but for the first two ones, it was actually enough. If he had continued the movies, I wouldn't have been happy about it but he making n°1 was great. At least for me.
And Voldemort was actually creepy in there at least.
