I just realized I had yet to get around to reviewing these movies, two weeks after the fact.
Let's keep it simple.
1. Dark Knight is awesome. Go see it on the big screen if you haven't already. Heath Ledger steals the show, though I don't think he's quite Oscar worthy. It's less dark than the first movie but the fight scenes still suffer from being shot far too close.
2. I honestly like Hellboy 2: The Golden Army better. Visually, it's a much more interesting film and not just because of the costuming and make-up - the cinematography is amazing, as you might expect in a DelToro picture.
