I'm afraid I haven't seen it. The horror elements put me off initially but it was also around the time when I was more American TV centric.
I always found Arrested Development a curious one. Initially I enjoyed the storytelling which as you say was very focused and aware of its running gags and character beats. But the comedy always seemed centered around very basic "believable stupidity" stuff with Gob and Tobias. In the pilot I thought Buster was going to be fun too but quickly became disconnected from his squirmy-ness.
As it went on I became less of a fan as things got whackier and Michael became less sympathetic to me. That coincided with me discovering that a lot of people I now follow online all thought it was one of the greatest comedies ever. I really struggle to follow that. I understand that there is a lot more to it than the average network comedy but it was always so silly that I never thought it could compare to shows with some genuine heart at their core. But that's obviously my whole perspective on comedy in general so that may not surprise you
I will catch up on the new episodes but doubt at the moment that I would have time to write about them. And it's that curious position where I'm not sure I'm adding much to the discussion by reiterating why I don't rate it as highly as everyone else.
