Sympathy for the Underdog
A yakuza gang gets driven out of Yokohama by a big gang from Tokyo. They relocate to Okinawa to violently start over.
More of the same from Fukasaku (if you've seen any of his 70s yazuka films, and there's more than a few, you've essentially seen this.) But I love this same; so to me, it's not a fault.
Sympathy? Well, maybe not, because there aren't really any good guys here, but at least they have some reasoning for what they're doing. Fukasaku manages to keep some substance in an otherwise very stylish movie. But, then he is the king of yakuza, after all.
