When did this show become a caricature of itself? I started watching Big Bang Theory after I heard Mayim Bialik talk at my temples STEM fundraiser. I watched seasons 3 and 4 and then watched 1-6. But since around season 8 it seems like all of the character's have just become caricatures of themselves. There's no development, only joke after joke.

I'm catching up with season 10 now. Please tell me if I'm completely off base
