It's more of the same, but in Season 2 it's about Leonard trying to figure out what went wrong with his shot at Penny. Unbeknownst to him, she is longing for him as well. A lot of fun episodes with a stellar cast. The characters of Sheldon, Howard, Leonard and Raj make this work. But it's Penny that brings a nice balance to the series. I highly recommend this as a Buy for sure. If that's not enough for ya, this season also sees cameos by the likes of Summer Glau and some crazy dude by the name of Charlie Sheen.
