More love for Catch-22. It didn't really follow the book, in fact it kinda did its own thing. BUT all the main characters were there and faithfully represented, and many minor ones as well. Also, the tone of the book, with its nonsensical, nonlinear approach was reproduced in the movie. You didn't know what the hell was going on half the time, but you could put it together, and upon subsequent viewings, you realize how brilliantly done it is. It starts off funny, some of the humor is a bit dark, then at some point you realize it's not even a comedy anymore, but a serious, cynical commentary on war. Then it gets all silly again at the end. Most importantly, the basic plot was pretty faithfully followed.
Hate for Dune, the David Lynch version. It seemed like every chance he had to make something look weird/cool, he went for it, to the extreme, and it didn't much matter how badly it detracted or distracted from the story. Plus, with all the stuff that had to necessarily be cut out, why add shit that wasn't in the book in the first place? I hate that. I've never seen the Sci-Fi Channel miniseries version, probably never will. I've heard good and bad about it.
