At the end of the second season the four boys leave to conduct research in the arctic and Leonard and Penny finally realize that they have feelings for each other. Or at least Penny realizes she has feelings for Leonard. With the start of the third season we see our four boys return from their trip and our love birds finally have a chance to get started on their relationship. Over the next few episodes we see the ups and downs Leonard and Penny deal with as they become accustomed to being a couple. Episodes that showcase that fairly well are "The Cornhusker Vortex", "The Jiminy Conjecture", and "The Wheaton Recurrence". Again, thankfully, the show doesn't completely focus on their relationship, which has been the downfall of many sitcoms in the past, especially ones where we have two main characters who we all wish to see get together and live happily ever after. What makes this show stand apart is not only the excellent character of Sheldon, who really comes into his own this season, but also the camaraderie between the 5 characters. Episodes that really focus on that are "The Creepy Candy Coating Corollary", "The Gorilla Experiment", "The Psychic Vortex", "The Precious Fragmentation", "The Staircase Implementation" and the season finale "The Lunar Excitation".
What also makes the show stand out is its obvious love and excellent use of science fiction culture. We see this cover a broad range of subjects from comic books, video games, movies, clothing, and most especially dialogue. One episode that really cover this well is "The Excelsior Acquisition" which has the very special guest star of Stan Lee.
Now the show has been released on Blu-ray and we can watch all the hijinks of the past season. Naturally the sound and picture quality are very good when it comes to Blu-ray, but there isn't too much in the way of special features. The most we get is the cast talking about favorite episodes, a set tour with Simon and Kunal, and a gag reel. It would have been nice to see some interviews with the show's creators to see how they come up with the dialogue for the show as well as the plots for certain episodes. Perhaps as more seasons come out we will get to see that, but for now we will have to make due.
All in all Big Bang Theory is a fun little show that really be enjoyed by anyone whether you're a fan of comic books/video games or even if you just like watching four very different people get involved in ridiculous situations.
