If it doesn't just have to be movies, you can also browse svtplay.se for lots of tv shows, many of them also available with subtitles.

Do you think you'd drama/psychological thriller/a bit of horror in one film? If yes, there is a movie called Låt Den Rätte Komma In. (The Amerikan remake, Let Me In, was ok, but didn't do the story justice). And then there's this the classic youth drama. (Warning! Offencing language ahead ;) ) It's called Fucking Åmål (Show Me Love when released abroad). And Lastly, another classic: Mitt Liv Som Hund från '85. Those are the ones that came to mind right now. Hope you enjoy dem: they are not very similar at all, but neither are Onskan and Kopps :D
