This is a good story about how a person can rise up and make something of him/herself.
The backdrop of Jamaican culture is brought to life quite nicely and I very much like the cultural influence be it they are pretty subtle. Being from the Caribbean myself, I can very much identify with much of the non-western cultural issues which aren't in-your-face obvious, but are definitely there. It might be handy to turn on subtitles because the accent will be very hard to understand if you have not been into contact with the Jamaican dialect much. The acting is pretty good, with my personal favorite being that of Rude-boy :) Don't expect an extremely good or complex plot, but it is a nice movie to watch.
Moral of the movie: You can be or become anything or anyone if you have a spec of talent and put hard work into it. (Which basically is the embodiment of the American dream right?)
