Heck yeah this was a fun movie. Like others in the comments, I picked up on the similarities to movies like Smokin' Aces and Guy Ritchie's stuff, which is probably why I liked it so much. It was chaotic at points, but the way everything tied back together by the end gave it some great payoffs.

Took my Dad to go see it, and while he had fun, it left him confused. He described it after as "Brad Pitt boards a train in Tokyo, gets off in Kyoto, and total chaos ensues in between." And it's not inaccurate.
