Leonard Hofstadter and Sheldon Cooper are both brilliant physicists working at Cal Tech in Pasadena, California. They are colleagues, best friends, and roommates, although in all capacities their relationship is always tested primarily by Sheldon's regimented, deeply eccentric, and non-conventional ways. They are also friends with their Cal Tech colleagues mechanical engineer Howard Wolowitz and astrophysicist Rajesh Koothrappali. The foursome spend their time working on their individual work projects, playing video games, watching science-fiction movies, or reading comic books. As they are self-professed nerds, all have little or no luck with women. When Penny, a pretty woman and an aspiring actress from Omaha, moves into the apartment across the hall from Leonard and Sheldon's, Leonard has another aspiration in life, namely to get Penny to be his girlfriend.

Can't Get Enough
13 May 2008 | by (United States) – See all my reviews

I didn't expect much from this show at the beginning of this season, but I have been pleasantly surprised. It has actually become my favorite show this year.

Now, with only one new episode left this season I will miss it over the summer and hope to see it back next year (PLEASE CBS!!!).

There are so many aspects of the show I like. First, I love how various aspects of the nerds relate to the folks I know (mostly in IT). Second, I love how the show flirts with the stereotypes, such as the dumb blond, but doesn't quite go there. Penny is not dumb, and Raj can be quite social if the circumstances are right. The blending of intellectual and ridiculous is also very well done, so that neither is overwhelming.

Keep it up, and keep this on TV!
