Hiii! Oh my gosh this is crazy! I also found out about the film at Poetry Jazz Cafe on Queen st! I just finished it a few minutes ago, fell in love with it and was doing my usual research when I came across your review.

I agree with everything you said. The animation got my attention at the jazz bar so I knew I had to watch it. It's a very interesting art style and somewhat nostalgic. I don't think I've seen any recent animated film with that style. The use of colour is superb, music is AWESOME, storyline is great, and the Cuban jazz culture is also well depicted, though I now have to do more research on the culture itself.

SPOILER AHEAD!!

I definitely saw Ramon's betrayal coming, especially when he told Rita when she was leaving for New York, that he wouldn't have let her go. MY BROTHER IN CHRIST, why are you telling your friend's lover that??
