Tv Season Info

In series 4 of the sitcom, Sheldon (Jim Parsons) begins an unorthodox relationship with an equally brilliant—and equally awkward—neuroscientist named Amy Farrah Fowler (Mayim Bialik, who is bumped from recurring cast member to series regular by the end of the season). Meanwhile, Leonard (Johnny Galecki) starts dating a new woman, but there's only one problem: She's Raj's (Kunal Nayyar) sister, and he's not too happy about it. Kaley Cuoco and Simon Helberg also star.

Critic Reviews for The Big Bang Theory Season 4

All Critics (9) | Top Critics (2)

[The Big Bang Theory] became a great show - and, perhaps not coincidentally, jumped about 30 places in the Nielsen ratings, into the Top 10 - once Penny stopped being the only female lead.

The show is now able to spend large chunks of each episode focusing only on the women, and in the process has made Penny a much more well-rounded character rather than just a foil for the nerds.

Mayim fits in perfectly in The Big Bang Theory cast and played off of Kaley Cuoco just as well as Emmy Award-winning Parsons.

The Big Bang Theory is absolutely back with a vengeance.

Sep 27, 2013 | Rating: 9/10 | Full Review…

The smartest sitcom on TV faced a choice going into its fourth season: evolve or stagnate. Surprisingly for such a huge sitcom, Big Bang Theory did the former.

There's nothing here that seems even remotely original.

Sep 27, 2013 | Rating: 1.5/5 | Full Review…

Jim Parsons and Kaley Cuoco's interplay remains the show's secret weapon.

Sep 27, 2013 | Rating: B | Full Review…

The comic commentary may be poking gentle fun at nerds, but the real target of the show's sharp satire is the arbitrary, self-serving stupidity of mainstream culture.

You want flat-out funny? Look no further.
