Be Cool is not a great movie by any stretch, but it is far more entertaining than the reviews suggested. To be clear, my expectations were low; I only watched it because it came up as a 99¢ rental on iTunes. In the end, I was pleasantly surprised.
My first surprise is that John Travolta turned in a decent performance. Normally, I find his acting horrid. I usually have the impression that his screen time is about advertising that he's John Travolta and not about his character. Yet, this time around, I was able to believe that he was Chili Palmer and not the usual giant Travoltan ego.
I did find the doconstructuve humour quite funny. Though it's not particularly original, it is well executed. However, it does require a good attention span. I think one has to realize that the entire film is the punchline for the premise set in the first scene to find the humour.
In the end, not a great film; but I thought it was 99¢ and two-hours well spent.
