Pastor Rob's role on Young Sheldon is evidence of just how much The Big Bang Theory spinoff's tone differs from the earlier hit sitcom's style.

I totally agree. The show has moved away from being a Big Bang Theory prequel to another dysfunctional family comedy. Mary and George are constantly fighting, Missy is miserable and through all this, Sheldon is adjusting to becoming a college student.
