[quote name='2Fast']It looked good for "Trials and Tribble-ations," but that episode was purely for fun, and I'm sure the movie will be more serious.[/quote]
They could do worse than to emulate "Trials". That was light-hearted, but they treated the source material respectfully, more than I ever expected.

I'm honestly not that much of a stickler for canon, so I don't mind if they retcon things a bit. Although I suppose that since it is a younger Kirk and Spock they are dealing with, it could look more like Enterprise (and work) and less like TOS.
I still don't think the movie will be any good

I'm most worried that he prefers people know nothing about the series. I can see why he says that, from his perspective. But honestly -- if that's the case, then why make a story with characters that have been around for 40 years.
The only reason existing Trek fans would hate it is if it egregiously violates canon, or is colossally stupid, or just feels wrong somehow. You know, like dune buggies in space.
It could work. Witness the new Bond in Casino Royale, or for that matter, Star Trek IV. Or the first half or so of Superman Returns, which I thought was absolutely brilliant in the way it catered to both new people and longtime fans. But if he prefers people who know nothing about Trek, I don't see how it can be particularly deep or compelling for those who know everything about it.
I also don't find the idea of Young Kirk and Spock exciting. I don't know what it would add to the series, or to the characters that hasn't already been said and done. I certainly hope it's not the launching pad for a new series.
Is McCoy in the mix? You really do need all three. But then it starts getting silly.
