I've heard nothing but extremely mixed things about Hancock, with everyone basically saying that some of it's awesome but some of it's terrible.
Conversely the early word on Hellboy II is pretty great.
The Dark Knight hasn't screened yet but it's BOUND to kick ass.
As for Hulk, it's hard to say. I really hope it will kick ass but the trailers don't do it for me. I've heard the script is great, though, and Edward Norton is one of my favorite actors. But I loved almost everything about Ang Lee's "Hulk," so it's very possible I find this one too mainstream.
