The gang continues their winning ways in Season 4 with the addition of a couple of new characters as well as expanding that of an existing character already on the show. Season 4 is best remembered for giving the girls time to play in the sandbox that is The Big Bang Theory. In the Season 3 cliffhanger, they had set up that Sheldon would have a potential love interest Amy played by Mayim Bialik. What could this union possibly bring us? A lot. Mayim is both odd and fascinating to watch at the same time. Her mannerisms and the way she talks is very bizarre, but you just can't take your eyes off her and she usually has some of the best jokes in her delivery.

Also joining the cast as Rah's sister is Aarti Mann as Priya, the love interest for Leonard. Melissa Rauch who had a small part in Season 3 gets to see her role expand into a series regular as Howard's main squeeze, Bernadette. I like her a lot. She is funny. Overall, this season is great. If there is one criticism I have is the lack of "star cameo's" like the previous season. I did like that Katee Sackoff returns as the object of Howard's desires. Also on board was George Takei, Levar Burton and Steve Wozniak. Not to be outdone is Wil Wheaton coming back as Sheldon's arch nemesis.

Highly recommend this as a Rent. For me it would be a Buy.
