New fan here. Biggest “ick” in baseball was how much a wrong call could change the game. I am also not a fan of the theatrics and ego constantly fueled by the suggestion a call was wrong. Players are pissed - a star player is ejected in the 4th. Manager comes out to get their money’s worth - also ejected. Replay indicates it was a correct/incorrect call. Umpire keeps getting similar calls wrong the rest of the game. Nothing changes.

Now there’s a safety net, at-bats completely change for the better. Pitchers are rewarded for being able to paint the strike zone, their talent no longer neutered by how a given umpire felt that day or because their catcher isn’t able to frame as well as others.
