it's one of those movies like napoleon dynamite, you either think it's great or think it's shit.
it's basically a very quirky movie, with very quirky characters. It's the type of movie you'd expect Phillip Seymor Hoffman in (but he's not)
off topic - If you want to see how weird and depressing a movie can get rent Love Liza, it stars Hoffman
