You're right it's different....it's a sport that has come to a sensible set of rules regarding video replays over years of iteratio that everyone, fans and players alike is pretty much happy with and rarely gets in the way of a good sporting event.
Clear and obvious
is in the laws of rugby, because it went through this stage of using VAR to make sure decisions were 100% technically correct and everyone agreed it was awful and killed off the enjoyment of the game...so the rules evolved to strike the right balance between catching every minor transgression, and actually having an entertaining sport to watch.
Football will get there eventually. In the meantime we'll just have the put up with the 'drama' of VAR
