I haven't felt too strongly about The Big Bang Theory in a long time, and the first two episodes of the season are no exception. While the addition of Bernadette and Amy have been welcome, the show is still riding on its premise, rather than developing something more substantial.
Of all the plots last night, none were particularly good, but Amy's reactions to everything remain golden. And Penny finally got an acting job! One of the most disturbing/funny parts was the incredibly homoerotic scene of Howard and Raj kissing via mechanical proxies. That they did it in the first place was weird, and then it kep going.
The long-term plot developments seem to be headed for Penny and Leonard getting back together. The writers retcon Penny and Raj by making it so that Raj was way too early, if you get my drift, and the long-distance relationship between Leonard and Priya obviously won't work.
