If you liked Machine Girl, Tokyo Gore Police or Versus you'll love this.
Starting with an homage to Rambo, Tak Sakaguchi's "Yakuza Weapon" quickly ascends to the realms of tongue-in-cheek over the top violence and gore that only Asian cinema seems to reach.
Tak Sakaguchi plays Shozo Iwaki, the son of a Japanese Yakuza boss, who returns to Japan after 4 years as a mercenary in South America to avenge his fathers death.
If a Hollywood Good Guy can implausibly be missed by a machine gun at point blank range, or outrun an explosion in slow motion, then Shozo can be missed or dodge 10 automatics, and surf the explosion to the Baddies tent! Plus homing sticks of dynamite... catching RPG's in your bare hands... spikes on the bottom of his shoes that'll put a hole right through your head... you get my drift.
It's hilarious. Many laugh out loud moments, and spontaneous applause at the end (only the third time I've heard that in a UK cinema).
Highly recommended.
On a side note, there is one scene where Shozo walks up a stairway killing all the foes he meets on his way, that was supposed to be shot in one take after 2 hours rehearsal, but they needed 2 takes because Tak broke his neck during the first take!
That's dedication for you.
