I saw it a few weeks ago and, honestly, I was left with a similar feeling. I mean, it's not a bad movie, but it didn't blow my mind either. It's the typical movie for a lazy Sunday when you don't want to think too much. The return of Cameron Diaz and Jamie Foxx is what sells it, but you can tell they didn't put much heart into the script. Like you say, it works, but you forget it a minute later.
