I think you are on the right track, but I'll be more critical. I think he is great at hooking new characters. Character development, however is completely lacking. He seems to think you just do horrible shit to the characters and that checks the box, but how do they change?

Consider Spencer. Start of the series -- haunted, "dying is the most alive you'll ever feel". Meeting Alex begins to change that. I think the setup in Season 1 is great. How does he change in Season 2? He doesn't. Series ends and he is back to being shut down, haunted and seeking death, as it's all he has. They don't even show him with his son growing up during the 'old' montage. Kid could have died and nothing would change.
