Love this show.
I love Dan Harmon because of Community, and have enjoyed various Adult Swim-style shows that have been recommended to me by friends (R&M was one of the most heavily recommended). But having watched S1, I'm not continuing with it. I don't think it's as funny or edgy as everyone else seems to. It's not as caustic as some other shows that I enjoyed up to the point where I didn't (Aquateen Hunger Force comes to mind), but it has that same vague air of being grating past the point of amusement.
