The Big Bang Theory has had some great season finales as well as some that were rather unimpressive. The advertisements for tonight's episode ("The Commitment Determination") boasted crazy cliffhangers and big changes, but I don't know that audiences really received those. Take a look at the storylines that took place...
Bernadette finally convinces Howard that they need to kick Stuart out of their home, but even she can't follow through when they learn it's his birthday. My problem: they've known Stuart for YEARS and have hung out more than a handful of times... how do they have no idea when his birthday is??
Season 1: Leonard and Penny go on their first date.
Season 2: The guys head to the North Pole for three months, while Penny wishes she wouldn't be away from Leonard for that long.
Season 3: Penny and Leonard have casual sex while Sheldon meets Amy.
Season 4: Penny sleeps with Raj while Howard feels emasculated due to Bernadette's new job.
Season 5: Howard heads to space and uses a flashback to tell the story of his wedding.
Season 6: Leonard heads to the Black Sea for four months, while Raj gets dumped by Lucy and overcomes his selective mutism.
Season 7: Penny and Leonard get engaged, Raj and Emily have sex, Stuart's comic book store burns down and he becomes Howard's mother's nurse, and Sheldon hops a train to avoid dealing with all the changes around him.
Not as interesting in comparison. Plus, the previous season's finale was much more "cliffhanger" with Sheldon off to ride the rails!
