Saw Zodiac and Black Snake Moan.
Zodiac was one of those movies that was good all around but won't really leave you breathless because it is based on actual events and we all know what eventually happens. It is a great story for those who've never heard of this particular killer but doesn't really deliver a satisfying punchline a great piece of fiction like Seven can muster, for example. I'd probably give it a 6.5 or 7/10.
Black Snake Moan was one twisted ride but somehow I think the writers were able to pull this story off. It's one of those movies where everything outrageous but consistently so. Therefore, a part of you is able to just leave your brain & rationale at home and simply enjoy this movie. 6/10
Perhaps I'm a tough critic but 6/10 is considered a pretty high score for me
