Why Community Season 2 BLOWS

The writers of Community are their own worst enemy; they seem determined to see themselves fail. But, instead of doing the normal thing and writing themselves into holes they can't get out of (aka Lost), instead they write themselves onto a dry and barren wasteland of nothingness. At least in the former, there's something going on, even if it doesn't make sense. 

At the end of Season 1, they manage to resolve every interesting conflict and character dynamic they have going for them.

Troy and Abed's weird, and sometimes awkward, friendship gives some of the funniest material. At the end of Season 1, Troy moves in with Pierce and all he seems to do is "Old White Man Says" twittering. Pierce isn't even saying the wildly inappropriate and wildly funny sexist/racist things he usually says so what's the point? Troy and Abed barely interact.

The study group decides to stop taking Spanish class. The writers try to compensate for denying us the creepy "Senor Chang" as professor, by keeping him around as a student. He morphs from a ball-busting and feared Senor Chang, into a sniveling "Golum," begging them to let him join their super cool study group. It's just annoying.

Jeff and Britta's relationship: feelings of mutual hatred and sexual tension, comes to an end when 1. They do it, and 2. Britta misguidedly declares her "love" for Jeff. There is nothing there anymore; it's all dispelled.

They morph into a 7-headed monster. There are no individual stories, personalities, or conflicts. They all go from place to place as one unit. Each character has been flattened out into a caricature of their former selves.

Finally, the show is not funny. There are elaborate and complicated scenes that are supposed to be situationally funny (such as when they get trapped in the Space Shuttle simulator) but it just comes out forced and flat.

And then they add in the "feel good lessons" to the ends of the episodes that are VERY not funny. Why are they channeling Full House and Saved By the Bell?

"The contest doesn't matter. What matters is that we have each other!" Annie

"The most important tool is respect because if we don't respect each other, we die." Jeff

This is the most intense, vertical, steep nose-dive I've ever seen a show take, and yes, I have seen Heroes.
