Although Dan Harmon wont be returning, I’m really looking forward to the new season 4. Appartemt, Sci Fi thinks there will be references to Huger Games and Star Wars and generally, it looks pretty good from the trailer:

I’m just very slightly worried that this new season 4 may go as far down the toilet as Big Bang Theory who’s latest series is, imho, almost unwatchable.
