I had mixed feelings about Will Smith’s Hancock when I saw the first previews-it looked like a comedy about homeless superhero. And for the first part of Hancock, it is a comedy about a homeless superhero. This Will Smith movie shows us a superhero without a Fortress of Solitude-he lives in a ratty mobile home, who hates kids-he tosses one into the sky and seems to debate with whether or not he should catch him again, and no one appreciates him, being around at all-everyone in L.A. would like it if he would move to New York. This is fun…
