This season creator Chuck Lorre and co. focus on the ups and downs of Leonard's relationship with neighbor Penny where they constantly go from intimate to strictly friendly to intimate again providing some genuine laughs with the conundrum of where they're headed in their relationship. The season packs the laughs with the writers relying on the humanity instead of taking these potentially cliché characters and turning them in to caricatures. Definitely it's one of my favorite television shows right now and season two is worth the purchase.

As for the DVD, we're given three features that are fun watching but ultimately feel like the creators had nothing else to offer in the way of insight toward the show so instead there's more focus on production and the mathematics on the show. However there is the funny nine minute gag reel that shows the crew fumbling lines and swearing more than expected. "The Big Bang Theory: Physicist to the Stars" is a ten minute puff piece that reiterates the information we received on the first set: There is a real physicist on set who checks the mathematics and consults with the creators. Finally, "Testing the Infinite Hilarity" is an enlightening fifteen minute featurette that explores and explains how the show wanted to evolve from the first season and how deeper we got to know the characters which pretty much validates why second season is so much better than the first.

"The Big Bang Theory" just continues to evolve from a trite premise in to something that's more focused on character development and truly interesting and original comedy that opts to keep its stance and not dumb itself down for the audience.
