Prerevoltionary Cuba was just awesome: night bars, good music, alcohol and prostitution. Then the communist came and made it such a bad place where great piano players have to polish the shoes of tourists. If you want to get a different perspective, watch Soy Cuba.
I enjoyed the setting, music and generally the mood most. I appreciate the art direction, especially backgrounds are amazingly detailed, character animations lacked though in my opinion. The weakest part is the story, especially considering the very original and interesting time setting, ending is weak and very unlikely to happen. It's worth watching for the art style and music at least.
