## Reception

The seventh season received critical acclaim. Oliver Sava of The A.V. Club criticized some of the humor, particularly stereotypes written for the female characters, although noting that "these actors make it very funny", but praised the series on a whole; "the major strides made with Sheldon, Penny, and Leonard compensate for some of the more distasteful humor, making this a strong start for this show's seventh season". Carla Day of TV Fanatic wrote that "There were definitely some funny moments, but in its entirety it wasn't one of my favorites". Euan Ferguson of The Guardian wrote that "The Big Bang Theory is now pretty well established ... And just gets ever better".
