What got me watching this movie was the advertisement that this movie is like South Park directed by Tim Burton. I agree with the South Park part. The movie deals with elementary school kids with anarchistic humour involving lots of comical violence, cursing, bodily functions and bizarre incidents that make so many, including me, loving that show. Also this movie.
As for Tim Burton, he directs visually impressive and original movies, that deal with a character, that doesn't quite fit the surrounding world. None of the descriptions above quite fit Terkel in Trouble. The characters are quite normal types. Anyone knows the types, bullies, wiggers, vain girls, teased fat ones and crazy substitutes from their own days at elementary school. I think a proper tag line would be "South Park directed by Sam Raimi". At least in the Evil Dead days Raimi was famous for enjoying both torturing his actors while shooting and enjoying a lot of violent humour inspired by the Three Stooges.
So it was a very funny movie. It wasn't actually a very original one, the key mystery is way too easy to figure out, but I was laughing too hard at things like a fork in the eye, a sledgehammer to the crotch and biting a kid's ear off in a battle, to really be bothered by it. Even the South Park boys would be jealous.
**** The best part: Instead of the best scene, I'd like to describe my favorite character. That is Terkels alcoholic sailor-uncle. A very violent, ignorant and nonchalant he may be, but loving Fernet Branca so much makes him a really twisted character. And also an enjoyable one.
