I enjoy watching How I Met Your Mother, it's a sentimental favorite. There aren't many shows like it left. It has alot of heart and wit but it's not always knockdown funny.
However, I can't think of an episode of Big Bang Theory that I'm not laughing or about to cry because of the jokes. You don't have to be a nerd to get the humor, it's reflective of societal norms and values. I just enjoy the chemistry of the cast. So overall, it's my new favorite.
