I love Big Bang Theory. It's my current favorite TV comedy and one of my current favorite TV shows but... it kind of annoys me that they start story lines and then just drop them. This season they started with the Raj/Stewart "are they gay" storyline and then just dropped it. Then added Sheldon's hot assistant, Alex as a possible wedge in Leonard and Penny's relationship and dropped that and it appears, the character too. Shouldn't these decisions be made in creative meetings BEFORE they start shooting?
