I used to be a continuity freak but now I say screw it...
Comics such as All-Star Superman have proved to me that all you need is to get the essence
of the character right and good things will follow...keep what works and discard what doesn't.
Besides, continuity is not nearly as realistically obtained now as it was from the 60s to the early 90s, through which you could more easily suspend your disbelief in the sliding time line. But now it's just been too
damn long to maintain that time line.
