The only critique I would offer is that there seems to be a historical disconnect between the scenes in the animation and the news headlines and the soundtrack - maybe not - I don't have the time nor inclination to do the research.
I'll bite my tongue about the historical veracity of the knife fight, the fedoras and the dandy clothing. Those are my personal opinions anyway so I'll keep them to myself. This time.
Otherwise, I like it. The animation sequences are good. They are obviously done by someone, or with extensive input from someone who understands/dances tango.
