First off, I'd like to say that I'm not voting 10/10 not because I think it's the best film of all time. It's because it's one of the few gay themed films I've seen that wasn't a major production like Broke Back Mountain, that is actually decent and is a film that I'll probably watch again.
Everything about the movie is believable and like-able. The gay characters are not just a walking collection of stereotypes, and the actors do their job well enough that you actually believe the characters love each-other.
The reaction of the parents and the townsfolk exactly what you might expect from small mountain town in Bavaria, which is a nice change in setting for a gay themed film which would usually take place in a city with lots of clubs.
Asides the drama, the film is filled with some great humor and is really more of a romantic comedy than a drama. But if you're going to try and find this online, because you didn't buy a copy,beware, because if you don't understand German and need subtitles, there are several online versions floating around with inaccurate subtitles, in which much of the humor is lost, and even some elements of the plot become lost as well.
