u/Interroggation

I watched it 10-12 years ago ( maybe a little less) He is 7-13 years old, probably has dark hair. I think the opening scene is a house being completely thrashed from food. In the movie, there is also a kid who is allergic to everything. It is probably an European movie, with only a one word for title, possibly meaning "bad" in english. In the end of the movie, all the bad tempered kids come together and become good tempered. So its kind of a coming of age movie. I watched in on HBO (Adria)
