I liked it and managed to watch it to the end despite not being a fan of this type of film.
I think one of the strongest visual images was the guy on the rocks who fell in the pool. I would have used that image a lot sooner in the piece myself. I agree it was perhaps too long but then again for those who enjoy this sport its maybe not long enough.
Music worked and it was well edited. The only thing I can criticise which has not been mentioned so far is the end titles. Just a tad to quick on one of them as I was not able to read it all in time.
Good effort, stay lucky and enjoy!
