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?

Oliver Sava AV Club I used to think the Sheldon/Penny pairing was the best on the show, but the Amy/Penny dynamic has become my favorite relationship on the series. Rated: B+ Sep 30, 2013 Full Review Ricardo De Querol El Pais (Spain) The Big Bang Theory brings us closer to the world of scientists, so despised in Spain, although portrayed as fans of 'Star Trek' and forced celibates. [Full Review in Spanish] Jul 16, 2018 Full Review Ellen Gray Philadelphia Daily News This remains one of the most dependably funny shows on TV. Jan 1, 2014 Full Review David Eckstein Zap2it.com The former Blossom star has integrated well into the crew of lovable nerds after joining the show in 2010. Sep 30, 2013 Full Review Carla Day TV Fanatic For a show that started out with Penny as a sidekick to the guys, she has come a long way. Rated: 4.5/5 Sep 30, 2013 Full Review Angel Cohn Television Without Pity What makes Big Bang Theory so entertaining is its solid ensemble, but there's always someone that burns more brightly than those around them.
