This is by no means a bad movie, it's pretty funny in places, its got a decent soundtrack, and it's fairly entertaining. However, it tries far too hard to adopt the same sense of humour of it's predecessor "Get Shorty", the result of which is a familiar plot full of copied jokes and lines from the first film.
The story follows Chilli Palmer (Tavolta) as he becomes involved in promoting Christina Milian's character as a professional musician. On the way he falls in love with his dead friend's (James Wood in an aweful cameo) wife Uma Thurman, who is really good in the roll, and very very attractive in her bathing suit! But he also has to avoid the russian mafia (?), a group of Hip Hop Gangstas headed by Andre 3000 from Outkast, as well as Harvey Keitel and Vince Vaughn who also want to produce Milian's first record. The tangled web of enemies is pretty well done, with all the bad guys ending up in trouble, and Travolta, Thurman and Milian striking large in the music industry.
The thing that really set's "Get Shorty" apart from this one is the cast, Gene Hackman was hilarious as "Harry Zimm", as was Dennis Farina as "Ray Bones", plus there was Delroy Lindo, James Gandolfini and the lovely Rene Russo. "Be Cool" is a mix up of actors and musicians in bad roles, with the exceptions of Thurman, Milian (Who is really lovely) and Andre 3000, who is actually pretty funny as the psychotic gangsta. However, Vince Vaughn's pimp character is ridiculously annoying, as is The Rock's gay bodygaurd character, and even Harvey Keitel and James Woods put in annoying performances. But the worst by far is Travolta, he's not really doing anything different here than he was in "Get Shorty", yet all the repeated lines and re-used jokes make his charcter loose so much of the cool credibility that he got from doing the first movie. It's a shame! I'd blame the writers personally.
So in conclusion, not a bad movie, but not as good as the original.
