JJ and his crew seem to be trying to restart Star Trek by re-writing it.
What JJ and his crew are doing is a dumb move.
To understand how this is a dumb move, lets look at the eras of Star Trek.
ENT ERA: 2150-2101
CAGE ERA: 2250-2264
TOS ERA: 2265-2269
TMP ERA: 2270-2284
TKOW ERA: 2285-2292
TNG ERA: 2364-2380
So JJ and his crew are tying rebooting TOS ERA, but the thing is TOS ERA is not a dead point.
Here are the dead point in the eras of Star Trek:
ENT ERA: 2150-2101 (DEAD)
CAGE ERA: 2250-2264
TOS ERA: 2265-2269
TMP ERA: 2270-2284
TKOW ERA: 2285-2292
TNG ERA: 2364-2380 (DEAD)
I do not understand why JJ and his crew thinks redoing the TOS ERA will save star trek. One thing is TOS ERA is not dead and it became TMP ERA and then, TKOW ERA.
Remember the old saying: "don't fix it, if it is not broken."
TOS ERA is not broken, JJ is trying to fix it.
as JJ's actions of "fix it even if it is not broken" will more like lead to the event of JJ braking it as he trying to fix something which does not need fixing in the first place.
JJ's messes around effects more than TOS ERA and JJ made more dead point.
ENT ERA: 2150-2101 (DEAD)
CAGE ERA: 2250-2264 (DEAD)
TOS ERA: 2265-2269 (DEAD)
TMP ERA: 2270-2284
TKOW ERA: 2285-2292
TNG ERA: 2364-2380 (DEAD)
This is the point that Star Trek is at right now because of JJ rebooting TOS ERA into his own JJ ERA.
Another dumb move by JJ and his crew is linking the Dead TNG era to his JJ ERA:

also Nimoy as the super-super old Spock is just sad:

Nimoy looks too old, unhealthy and sad. Some People said Shatner is too old and fat to play old kirk, but now seeing how old spock looks in this film, I have to say Shatner is the same.... if not a bit better looks for his age. 
Nimoy looks like a troll doll with vulcan hair and eye brows.
It is good to see Nimoy as Spock once more, but I think old spock needs old kirk.
