I was looking forward to watching a German crime- drama, having enjoyed the Spanish "Money Heist" immensely. With the first episode, I felt it was confusing, and had a couple of bad holes in the plot. Thought I would bail out, but continued to watch the series and increasingly warmed to it. Found it very funny in places. Am not sure if that was intentional, but it might have been. Certainly, for me, it added to the offering.
I got invested in some of the characters, notably Joseph and Rami.
"Goodfellas" it is not; but I got to enjoy it.
