Red State is well made and darkly entertaining. It's definitely not a "Kevin Smith" film but it is good.
Cop Out is a fun shallow buddy cop movie. Nothing wrong with that.
Zack and Miri is pretty funny, but it's no Askewniverse.
Jersey Girl I had absolutely no interest in. I only saw it the once and I'm not interested in seeing it again. It's pretty much a straight up drama.
