I watch movies to be entertained, Sleepless definitely did that. While not at the top of its class when it comes to crime action/drama, it had a lot going for it in my opinion. The fight scenes were well done, the scenery was dark but was still able to show off the glitz and glamour that Vegas is known for, and the story-line wasn't half bad. I was expecting to see a bit of Collateral in this, and I feel like that's what I got only with a bit more action and less Tom Cruise.
Don't go in thinking you're going to be seeing some Oscar worthy film, that isn't what this is. If you are expecting to watch a good crime action flick with Jamie Fox kicking ass then you will be happy with what you see.
