Had a good time watching this one, way more than I thought I would. Fast, funny and does not take itself too seriously. As the name clearly spells out this movie takes place pretty much entirely on a bullet train going from Tokyo to Kyoto. You have a bunch of hired killers, a briefcase, and even a very poisonous snake are on said train. We figure out what is happening and why they are all on a bit by bit almost at the same moments they do, especially the character called Ladybug (Brad Pitt) who was under the impression that he was going to get on, grab a briefcase and hop off at the first stop. That is not quiet how it goes and he is as clueless as we are why the fuck everyone is trying to kill everyone and we are all off on a very fun violent ride.
