This "Frankfurt" Tatort cranks up the weird-o-meter dial to 11. Hauptkommissar Murot is known for rather bizarre psychological fantasy stories, but this one tries a bit too hard with the "am I dreaming or is this really happening?" genre. Although produced in 2015, this was my first chance to see "Wer bin ich?". A more recent episode "Murot und das Murmeltier" had lots of magical elements of the legendary "Groundhog Day". The episode here seems to desperately follow "The Purple Rose Of Cairo", but left me somewhat dissatisfied with it's unbelievable conclusion.
The best feature of this utterly bizarre episode are the many cameos by well established stars of various Tatort teams, all playing the actors, not the characters. Fans of the series will enjoy that, especially the amusing dialogues. Besides that, I feel this is not one of the better outings of one of my favorites (Murot). The psycho drama was a bit much this time.
