Shortly after meeting the three ??? their clients, the long (felt 10 minutes) and to a large extent talks bullshit. So he calls the three ??? constantly Warriors of Twilight and be shed is the Castle of Light. Only to mystify the person, which is anything but a clever and seemed fake.
What is completely absent in the episode is the center; the story is progressing barely. The three stumble from clue to clue, but it does basically nothing. The whole trickles so in front of him and suddenly 20 minutes had passed. Voltage curve and Kopfkino look different.
The finish is also more bad than good success: the book I found the presentation quite as exciting because the three ??? come under pressure. In the radio play atmosphere lacking. Music, background noise and speaker can not convey the feeling easy. Where is the sense of threat, of hopelessness? I've really just been waiting until it's over.
Typically, the youngest three ??? - manner the resolution of the puzzle in the wake made by a conversation with the client. And the resolution itself, well, is quite ok, but tears it not out. This is really better.
Conclusion: No total failure à la Sonnleitner, but no follow-up, I would miss seriously. In my view, after it is also an expression of the fact that the authors at now 200 episodes (if we include the special effects) have it really hard to come up with can be even good, coherent story.
Edit: Have the Rezi minimally reduced by spoiler tendencies counteract.
