[BigTremor]

despite whatever differences there are the point may be he still evolves close to being the kirk we know in the end.

The worst thing JJ could do is listen to internet fans

Yes, but only Spock is Herbert.

Spock is not Herbert, He said it himself

 

[Franklin]

yes, but now Spock is just another nerd.

Yes, but only Spock is Herbert.

Spock is not Herbert, He said it himself

Well since Trek films usually cause damage TO Chekov, that's not really a problem.
