I'll start with this season. To enjoy this season, you need to expect dull moments, poor writing and annoying acting. This episode may be worth a high rating for this season, but for the series, it isn't that much. To balance out of expectations and overall feel of the show, I give it a 4.8, which rounds to 5 on IMDb. Now onto the episode, Sheldon was completely out of character (usual for this season). I would say he was about as dumb (or smart) as your average person. I suppose they forgot he is (was?) the smartest person in the world/show. Penny was being her typical- to-recent-seasons jerk. Leonard again is clueless. Raj and Howard still can't get along. Bernadette is continuing her caricature extremes. Amy was decent, but overall bore.
