Why? Because it's a one of a kind movie. The acting is superb (especially Bjork), direction assured and the musical numbers are great. Still, it's the most depressing film I've ever seen. By the end of the film I was crying practically non-stop. It's so bleak I don't think I'll ever see it again, but it should be seen at least once by everybody. It shows misery and suffering full throttle. You'll either love it or loathe it (I'm somewhere in th middle), but you'll never see anything like it again and you won't forget it. Just bring lots of Kleenex.
