It's a typical german comedy film made for kids and family and guess what: it's very cringe and unfunny. The acting is terrible and the script has a lot of plot holes, it just makes no sense. The camera work and quality is overall nice, thats why it gets 2/10, but the movie is just boring, cringy and was not worth the money at the cinema.
The story is very predictable and nothing new, they try to establish some kind of "youth speech" that doesnt exist and just makes it more cringe.
