The fourth season of The Big Bang Theory finds Leonard (Johnny Galecki) falling for Raj's sister Priya following his break-up with Penny (Kaley Cuoco). Meanwhile, Sheldon (Simon Helberg) finds romance with a neurologist who quickly establishes herself as Penny's new best friend. As Howard and Bernadette's relationship blossoms, Bernadette finds herself plagued by Bollywood daydreams starring Raj (Kunal Nayyar).
Big Bang Theory is a favored show in my household. We jump at the chance to watch it. I'm not a huge fan of the cover art for season 4, but you can't judge a series by it's DVD cover! We watched the discs in a matter of 2 days and will have a Big Bang marathon after we get the first 3 seasons back from friends. :D
What's great about it: comic references, star war references, pop culture, entertaining
What's not so great: Penny looks really bad on the cover, needs more extras
