It is surprisingly good for a german production. Acting is good and there are lots of fresh faces, which is not common in german television as most productions use the same actors. The plot is okay but nothing you haven't seen before no real twists or surprises, everything is pretty predictable. Also there are not many episodes and it still drags on.
I think the main reason why this show got so much attention is because of relatively unused scenario of the Berlin underground and the really good atmosphere. It gives you the creeps thinking how much of it could be real.
My only real criticism here is the shaky camera it makes the show unnecessary hard to watch and almost gives you a headache. I will never understand why people think this would be a good idea.
All in all I would recommend it if (and only if) you want to see a good german show, because there aren't many good ones.
