I'd have to say my favorite comic book to movie adaptation would be Batman Begins. It had a very good balance of action, drama, and story. It was a dark portrayal...but not as dark as Tim Burton's films. It doesn't hurt to have Christian Bale, Katie Holmes, Michael Caine, Llam Neeson, and Morgan Freeman as your cast. :D My second pick would go to Spider-Man and third would be X-Men 2. Wha's your favorites?
