Personally, I would have much rather have had Abrams and Co. just call this relaunch of the franchise a flat-out re-boot without jumping through the hoops of having Nero change the timeline...
...But that's just me.
No it isn't. it's me too.
Don't get me wrong, I enjoyed 2009, and expect to enjoy 2013, but yeah, I still feel that a straight reboot without ties to past Star Treks would have been better. And I'll use Batman as my frame of reference. Adam West, Michael Keaton, and Christan Bale all made fine Batman stories on their own without relying on each other.
