The Big Bang Theory continues to be hot and it is only getting better. The cast is really coming together this season and the show’s format is really starting to mesh. The obvious star of this season is the addition of Mayim Bialik as Sheldon’s equally weird “girlfriend” Amy Farrah Fowler. Her character is in a state of evolution and the formation of the new best friend girls made up of Bernadette, Penny, and Amy is a fun counter to Raj, Howard, Leonard, and Sheldon.
The Big Bang Theory seems to be following a bit of a Friends format with having Penny and Leonard continue to cross paths after the end of their relationship last season. The last minute twists in the season finale does change that a bit by involving Raj and his sister Priya as foils for the characters getting together.
Sheldon continues to be the reason to turn in…He’s like Felix Unger on speed. It is good however that they are developing the other characters and when they have their own episodes since it can be too much Sheldon sometimes.
