The first seasons were really good, the plot exciting, according to the motto "nothing is as it seems". The logic and probability of action was still OK. Season 7 is kind of weird and implausible Totgeglaubte reappear, corrupt are not yet corrupt, but then later. A constant back and forth and Jack slowly mutates Superman. Especially funny is that there is now a US-Merkel are, but this is sometimes really really embarrassing.
