I have an odd take on this movie as someone who was at the 1996 NPS, and is in the movie for about 6 seconds.
On one hand it is an awesome way to get people to see what we do and why we do slam. On the other hand it has perverted the slam, because people are using it a vehicle for there 15 minuets of fame. The irony is this is "slams" (as a whole) 15 minuets, not the poets who are in it.
As far as a production itself, it is very well done, but the plot of the move is just way off. I still have a hard time trying to get behind a team from New York. It's New York! You can't route for New York. They should have followed the Austin team from the same year. That would have been a movie.
I gave it a 5 based on the proliferation of "Sha clack clack!" in slam.
