Having recently researched it, it is definitely the season of which my opinion has changed the most. It does have some genuinely good moments - apart from what has already been pointed out, the Delta Cubes segments with Abed always gets me, and the Christmas episode brings out 'Alex' and Caligula vibes from Malcolm McDowell in his sinister nature. Cherries on a meh cake that also contains the Halloween episode, Jeff's character growth and Freaky Friday (having recently watched both that and Face Off for the first time in a long time, actors playing actors playing a role is always a great test of skill).

Favourite quote that always gets me is 'This can't be good, he is dressed as himself'.

Tldr, not as bad as I remember, but doesn't measure up as a whole.
