The cool things about The Big Bang Theory are maintained: we have Kaley Cuoco (Penny) and Geek Jokes. And things get better. Now, we have Melissa Rauch (Bernadette) and Aarti Mann (Priya). Ok, Mayim Bialik can also be cute, but not as Amy Fowler.
News on this season? A few. Leonard breaks with Penny, and gets along with Priya. Howard continues with Bernadette, and Sheldon keeps the intellectual relationship with Amy. And the poor Raj keeps alone… or mostly.
Keeps being funny to watch. Preparing for season 5 soon or later.
