Yakuza Zombie

The beautiful, beautiful title promises lots of stupid fun, the actual film delivers even more: A loving, slightly parodic homage to Kinji Fukasaku's jitsuroku movies, including riffs on trademark scenes and themes, and a justly byzantine plot. While the humor is actually funny.
Oh, and there's a zombie, who stands in for the misused and betrayed yakuza and comes back from the grave only to get misused and betrayed again, but, being a zombie and quite hard to kill, this time at least gets his vengeance.
The whole beautiful, surprisingly ungory (he's not a flesh eater, you see) mess is carried by the palpable enthusiasm of all participants. The film projects so much fun that the flimsy production values don't matter at all.
How much a novice to yakuza movies will get out of this is anybody's guess, though.

Darlings of the day:
"Yokohama has lost, the Giants are doing well and we can't have a funeral. We're the laughing stock."

"Hon, do you know what they call me?"
"What?"
"A bad luck fuck. Every man who sleeps with me gets killed. You're so brave."
"I like it."
