Bialik manages to steal scenes from Parsons as if she's been with the crew since, well, the big bang.

As wonderful as Parsons and Sheldon certainly are, and as terrific as a Sheldon-centric episode like last week's can be, too much Sheldon would quickly become too much. We're not there yet, but it is one of those lines the writers should be careful not to cross.

"The Big Bang Theory: Season 4" is arguably one of the series best, with adding a new love interest for Sheldon, which Bialik perfectly adds a new sense of intellectual humor to the group. With its unremarkable silly and drop dead scenes with Parson's and Bialik's characters, with a catty battle with Cuoco's and Galecki's girlfriend's, along with a standout hilarious side character cast, this fourth season is a huge hit.

Amy's high resemblance of Sheldon and Bernadette's romance with Howard gave the show a completely new and positive vibe. Especially love the interactions between Shamy!

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.

Funny, witty and interesting as usual. Parsons continues to shine under the role of Sheldon and the jokes are continuously very funny.

This season wasn't as good as the previous ones. There was way too much sexuality, and I don't like it. If I want sexuality I'll pick a romantic movie with slight pornography. The Big Bang Theory is supposed to be a comedy show! I don't mind if there's a bit of romance, but this was just too much. And usually Sheldon is funny, but in this season he was blunt and had no humor at all. Great season on behalf of the amusing parts, which were honestly very small and rare.

I can't believe this is a hit. Sub-par. I sometimes tune in and can't even muster a chuckle. The characters are one dimensional and there going to sci-fi movies and such are too predictable.
