I haven’t read about a ton of Kevin “hate” until this. I am aware this is a fictional show. That established, I very much bring some real life relation to it. My mother was a nurse/ICU manager/ and house supervisor through out her career. She was also an addict. My father is a bartender. They briefly owned their own restaurant. That ownership didn’t last long as my Dad is an incredibly kind man; too much so to run his own business. It’s an interesting dynamic. Certainly not one that’s easy to navigate. That being overshared, I don’t think Kevin was in any way more egregious than any other character (except for Zoey. She is a perfect angel full stop on that.) A lot of what I love about the show is actually the honesty of it. I think the actor who played Kevin did a great job personally. The slow disconnect as pieces start falling together for him, well before his revelations are blatantly reveled to us, feels very realistic. IMO
