The Big Bang Theory - Season 3 continues to explore the life of two socially awkward physicists. They would soon get a taste of the world outside the laboratory.
Somewhere during the run of a good character-driven sitcom like, say, Friends it reaches a point where the characters are so familiar that the jokes come easy but not so familiar that they breed contempt. The Big Bang Theory is right in that sweet spot.
Let's face it, what lifts The Big Bang Theory into frequent excellence is its one constant from the start: the brilliantly nuanced performance of Jim Parsons.
The Big Bang Theory, which is a very good show and not quite yet a great show, finds most of its predictability and inevitability inside of the legitimately great performance from Jim Parsons as Sheldon Cooper.
