German comedy is often a bit shallow and predictable. This one, once you accept the premise of the phones revealing everything in one evening, is delightful in its many turns and surprises. The dialogue is witty and clever. Yes, there is homophobia and other non PC things going on, but they take a turn and "fix" it again on the fly. And yes, it does carry a message: Communicate! Whatever the cost, not communicating is worse. My full recommendation.
