Ive seen it yesterday in Zurich, same concept I guess. with the filmmaker attending and asnwering questions... At the beginning they organised a crash curs for salsa, and after the movie there was a live band and some dancing.
The movie was way to to long. Some People walked out of the Movie, some could not cope with the generall style ( blurry,Handheld cam) I also thought it was bothering...almost gave me a headache at the beginning.
Would not watch it again, but as a whole the experience was nice
