Sacrilege!
Replay reviews for baseball is heresy.
I won't bore you with purity of the game, tradition, or the human side of the equation. Any argument that people make mistakes aimed at me is met with a smile and the words, "Yes. So what?"
It seems I am a lone voice in the wilderness saying, can we find a way to make baseball SLOWER? Do we REALLY, really need replay? And why the sudden (within a the last couple of years) is there a clamoring for this intrusive additional layer of flawed technology? Replay reviews are not fool-proof! Just take a look at the NFL or (e-gads!) College football!
But if that doesn't sway you and you want technology to overrule people, why have people umpire at all? Let's use 100% technology. Make the balls with locater beacons, have the field set up with sensors. Have a couple of 3D camera set-ups to automatically call balls and Stikes (it is really much easier to do than some think).
If you want to take the human element out of it, let's do it all the way. None of this namby-pamby appeal crap!
See ya
