Mensa-fied best friends and roommates Leonard and Sheldon, physicists who work at the California Institute of Technology, may be able to tell everybody more than they want to know about quantum physics, but getting through most basic social situations, especially ones involving women, totally baffles them. How lucky, then, that babe-alicious waitress/aspiring actress Penny moves in next door. Frequently seen hanging out with Leonard and Sheldon are friends and fellow Caltech scientists Wolowitz and Koothrappali. Will worlds collide? Does Einstein theorize in the woods?

Let's face it, what lifts The Big Bang Theory into frequent excellence is its one constant from the start: the brilliantly nuanced performance of Jim Parsons. Go to Full Review Ross Ruediger Bullz-Eye.com 04/03/2020
4.5/5
The writers and producers are playing something of a dangerous game, because some of the other characters, most obviously Leonard, are shrinking into the woodwork. Go to Full Review Tom Conroy Media Life 09/27/2013
Somewhere during the run of a good character-driven sitcom like, say, Friends it reaches a point where the characters are so familiar that the jokes come easy but not so familiar that they breed contempt. The Big Bang Theory is right in that sweet spot. Go to Full Review James Chamberlin IGN Movies 09/27/2013
8.5/10
Metcalf and the other actors have a relatively easy job in the premiere because the joke writing is so well done. Go to Full Review Read all reviews

matthias S @Thescreenasvor Jul 19 Season 3 is where The Big Bang Theory really finds its groove. The cast chemistry is fantastic, the friendships feel more natural, and Sheldon steals the show with some of his funniest moments. Leonard and Penny add a nice emotional layer without overshadowing the comedy. Not every episode lands, but the season is consistently funny, charming, and incredibly easy to binge. Definitely one of the show's stronger seasons. See more Michael A @Tomato547 Dec 18 Season 3 was a good season with great jokes.
