IMO, the business propositions that deserve the greatest consideration are those with a potentially high up-side while having a quite low potential down-side.

If PROMETHEUS could earn so much with an R rating and the difficulties it had, I have to believe that the chances of a couple of SW movies failing to earn back their production costs are exceedingly low.

I would be inclined to want a remake of the basic story-line of the OT and a reboot of the PT.

I don't believe the '77-'80 generation would ever consider any OT remakes to have matched or exceeded ANH or ESB. Curiosity and controversy would be the main drivers for that crowd, I suspect. OTOH, there would be a real chance that the younger generations might see them as equal or even superior.

In any event, if they are produced in a spirit of love, enthusiasm and respect for the OT, I think they could be much enjoyed by nearly all.
