Oh well yeah in like 20 years or 30 when this movie is a classic but they'll want to recreate the character for a new audience (I would expect a more serious and grittier version at that time) they'll probably try and do it maybe sans origin but I could see t hem starting over. I think the origin will be gold in the first movie and untouchable, though I doubt we'll see a SR treatment ever to Raimi's movies.
With that said, I don't think a restart is as vital. The only real thing I think that was a huge loss has been the multiple love interests and Peter's flirtation but it is subjective if just having one girl worked or not. It certainly dilluted the GG though. However, these films are nowhere near off track like Schumaucher was.
And that is a fact too though.
