I think the time travel/Spock Prime stuff was a burden to the film, in some respects. Was it neccessary? Should they have done a straight up unapologetic reboot? The expositional scenes explaining the alternate timeline are there for the core fanbase, let's face it. It adds nothing for the casual viewer.
As I digest the film, this is my growing impression. The inclusion of Spock Prime was an unnecessary and futile concession to the notion of continuity.
Oddly enough, its effect on the plot has a tendency to enrage the very canon-sensitive individuals that the device was designed to placate.
A better choice would probably have been to simply realize that those people were going to be enraged no matter what, and to just say "to hell with continuity" and reboot.
The main effect of this would have been to streamline the plot and eliminate Spock Prime. I think it is hard to imagine either of these changes would have had a negative impact on the film's appeal or box office success.
