I like Kevin James and well, Will Smith has been in some good movies, but Hitch looks like a really lame, predictable rom-com. I mean, I knew the entire plot before the trailer was half over. "Oh, Will Smith thinks he knows it all, well just he wait until someone throws him for loop... oh, and there she is!" Eva Mendes bugs the hell out of me too. I don't like her.
There are a couple funny bits in the trailer centered on Kevin James, but the rest of it isn't anything I would ever want to see.
