Bernadette is such a minor character, I barely even notice her tbh. Amy is funny, because she's just as awkward as Sheldon is... which is also the reason I find him funny. The only people that matter much are Leonard/Penny/Sheldon anyway. Those are who I focus on. The show started to follow more of a timeline over the last few seasons. There was actually a cliffhanger last season, and we don't know how Sheldon is going to deal with these new changes in his life. That's where this season is headed - changes.
I can't even at you guys thinking South Park, of all shows, is better than Big Bang. That's sad.
