Nominated for 1 Oscar:
Best Original Song
There is something hilarious in South Park being an Oscar nominated film. If you are used to the tv series (I myself don't watch it regularly, but I knew the characters) or have seen this film version, you know how politically incorrect it gets. And of course there's the swearing: for those hesitating, the Oscar nom came for the song Blame Canada (probably the only decent one) and not for Uncle Fucka or Kyle Mom's a Bitch. :P
But if you're ok with all the vulgarity (I was, with the most of it), South Park is a killer comedy with a veeeeery funny screenplay and a lot of memorable moments. It's never subtle, but it's smart and I am continuously surprised by the creativity of the writers. It IS an offensive crazy-funny animated feature.
My rating for the film: 8/10. Hilarious.
