I'm of mixed feelings on the episode last night. I like that the show is daring to go deeper into the characters, and make references to things a lot of the audience has never seen. But that has to be balanced with laughs, and last night those laughs were few and far between.
Plus it felt like a cheat to give Abed some great character development, and turn it into a practical joke of sorts and regress him back to normal.
As Abed himself might say, "Do or do not, there is no try."
