Couldn't find a thread for it, so I thought I'd start my own.
I finally got round to watching it tonight, and I have to say that I really enjoyed it. I've heard some people say that the first half is fantastic and the second half is terrible, but I thought it was all good.

The idea of a superhero who doesn't give a damn has probably been done before, but not enough, and Hancock pulls it off very well. Ray's wife being Hancock's 'ex' seemed a bit tacked on to make the story go, but it fitted, and it added an extra dimension to the story that worked well for the ending.
