You asked why I care so much for 1997 and I gave you my reason. And the reason is that they are the only proper self-contained SE out there. By self-contained I mean that they don't have references to some other non-relevant films (i.e. to PT). OT has been designed to stand on its own and did most successfully stand on its own for many years. PT is an optional back-story therefore people should not be imposed with PT references in OT if they choose to ignore PT. That is why 1997 SE is important as it is just an enhancement of the original versions. However for those who do care about PT there is 2011 version with all the PT stuff in it.
