I received a Bob's Burgers T-shirt for Christmas one year. No-one in my house had ever even seen the show, so I was curious as to whether or not it was good. I finally got around to watching it, and 100 episodes later, I can confirm: it's a really good show. Much more grounded than Family Guy or even the Simpsons, it's a funny and very warm-hearted show with fun and likable characters. Even the not-as-likable characters have their quirks. It feels kind of weird to watch an animated sitcom where I don't absolutely hate any of the characters, and have walked away from almost every episode so far thinking "wow, that was a really good one".
If you're looking for a delightful animated sitcom, Bob's Burgers is worth watching.
