I look back in on this thread and am amazed to see people still claiming it can not be prime because it does not look dated. Trek has had its visuals rebooted twice. A 3rd time has zero effect on the story or events, just in how we, the viewers see them unfold.
But there IS a way it can look Prime and still look Kelvin-ish. JJ did it with the uniforms in the Trek films. They weren't 100% TOS, but they were close enough to still show older fans, that 'hey, these are Starfleet uniforms.'
(The time before the Kelvin attack, those were...debateable.)
The Enterprise..looked (I use the term loosely) like the Enterprise of the Prime era..to a point. We still knew it was Enterprise.
(At least the exterior was, the bridge, well if I can't say something nice, better to close my mouth lol)
IMHO, Phase 2 and Star Trek Continues show that the TOS look can work, even if done just to invoke the spirit of pre-TOS/TOS prime.
I want story and characters to be well written as well as others do, but is it asking so much to tweak a few things?
