Hedwig and the Angry Inch

Think Rocky Horror but with better songs and maybe even a bit more cheek.
Now I don’t particularly like musicals, but once you throw in a bit of charactor developement the way this film has, you get an extra dimension that many don't. Chicago goes close (closer if they cast Kylie as the lead) likewise ‘Rio Bravo’ and ‘Moulon Rouge’ (had it been ½ an hour shorter) and even Singing in the rain, but there's still daylight between these and anything else in the genre.
