It was okay. They should have spent a lot more time on it. Most of the jokes were just filler and they repeated the same jokes a lot (and I'm not even talking about Cerebro). They had as many band references as Family Guy has random "this is like the time I ____" tangents. There were funny jokes interspersed throughout the riff (more than Quirk gives credit for, IMO) but overall it wasn't quite good.
