I am okay with the depiction of a galaxy at war, which is what is being built in these films. The original series implied that the 2240s and 2250s were, also, a time when the galaxy was at war.
I am less okay with the depiction of James Kirk. I am still struggling with believing him to be a competent captain, much less a captain who has earned the right to be the master of the Federation flagship. The TOS Kirk earned his promotion to master of the Enterprise
after proving himself as the captain of a lesser ship.
