It's a bad trailer. It's trying very hard to make this look like Another Will Smith Smartass Comedy, but it also looks like it took every piece of comedy in the entire film and put it in the trailer. The opening of the trailer is slow and stilted. That's just bad trailer-making, and I have no idea what the film will actually be like, or even if it will be even slightly good.

(Strangely, what this reminds me of was seeing a trailer for the Nathan Lane/Robin Williams The Birdcage which was edited to make it look like a Robin Williams Zany movie. Which it emphtically isn't; Williams gracefully spends most of the film as the straight man while Nathan Lane gets most of the jokes and Hank Azaria pegs out the camp-o-meter.)
