My main issue with the series is the escalation. Usually, when a series escalates, there is an external pressure. Be it money or just someone wanting the MC dead, but in case of this show, most of escalation felt unearned. These people didn't feel like they were struggling for money. There was no reason for them to keep pushing themselves to the extreme they did end up going. (With a singular exception of Lucy. She had a reason to go the deep end. But David definitelly didn't feel like he had a reason to ruin his life further throughout most of the show.)

Did I miss something?
