The Big Bang Theory is a great show, certainly one of the best traditional sitcoms on television currently. The first three seasons have by far been the best of the series. The fourth season saw a downward spiral, and the fifth season was complete garbage. Things have recently picked up for the show, with the second half of the sixth season improving greatly. Hopefully the trend continues. The second season, presented here on blu-ray, is probably the best the series has ever, or will ever, be. The audio quality is good, but not great. The video quality great, but not amazing. This is certainly the best the series has ever looked or sounded though. The supplements, however, are severely lacking.
