Series 1 I didn't like, messy, unclear, you fall somewhere in the middle: as if you are not watching part 1 of season 1 but part 6 of season 3 or something. Season 2 is very different (a lot has changed to keep and attract viewers, there was too much criticism of season 1 which caused many viewers to drop). Then it gets a lot better, although it remains unbelievable that everyone can constantly kill people everywhere and in every way. In broad daylight, on a shopping street, at an airport, etc. No one doing anything, no one getting caught or chased.
