This French slasher about a cabbie stalking a couple of dudes who ditched without paying was almost a goofy-fun-time, until the animated flashback to medieval Japan. I wish I were kidding.
I thought it was a dumb name too, but there's a surprising amount of gardening in this movie! For every brutal, violent scene of post-apoc hoodiemen savagely killing each other there are about 50 that are just some dude survivaling - and at least one time jerking off on his plants. Why do I feel like I'm not selling this very well.
