I like Moodysson's
Fucking Åmål and
Lilya 4-Ever obviously
I also like some older Swedish films from the 60s, 70s and 80s that you've never heard of, and that unfortunately are not available with english subtitles
The ones you mention are all relatively new films
I think Sweden was internationally famous for the "art films" of Ingmar Bergman and also the soft-core sex movies of the 1960s and 70s
These are not my favourites though, I just mean they're a big part of Swedish film history
