If there is overwhelming evidence to overturn the call, it will be obvious on the 1st look at all the angles.

If it takes multiple minutes to view several times in extreme close up and extreme slow motion to make a determination, then it's too close to over turn.

As for Danny Coale's catch, IMO, the call should have been "the ruling on the field is CONFIRMED". Which means there is positive proof the catch was made.

At worse, the ruling should have been, "the ruling on the field STANDS", which means there was no clear evidence the catch wasn't made.
