The rest of the IMDb reviewers have got it about right. This is a good film. Nothing special or brilliant, but it does what it sets out to do which is to make you laugh - and it does so much better than most films of its kind.
I started watching this expecting to change channels quite quickly. I only gave it a chance at all because Joe Pesci was in it - which is never a bad asset for a film. What happened was I found myself smiling quite a lot, and then laughing quite a lot. Not uproariously or uncontrollably. But out loud, and more than once.
Pesci is good - but so is just about everyone else. And the script is wickedly funny too. It's much less predictable than most of its kind, There are twists which are genuinely surprising and interesting, and the film stays pretty fresh (even though in truth it's probably 20 minutes too long).
I'm quite a harsh marker, so a 6 from me is quite a compliment for a film like this. Well-written, nicely-paced, silly without being annoying, and containing some funny performances and a lot of good moments, you will like this one if you give it a chance.
