I completely agree with you. Well said. No, this isn't a 'mirror universe' Plum, I do 100% agree with you. I had noticed the subtle curving of the TOS/TMP saucer was missing from the Kelvin pics, so this flatness carries onto the top of the saucer too, I reckon. This part of the saucer design survived right through from the original Matt Jeffries design to the TMP era. And as someone who drew the big E a lot, that aspect of the ship was always hell, HELL, to get right proportionally. Even doing it in CG is a huge pain (I gave up). It's a part of the design I have the hardest time accepting, funny enough. And funny it isn't the rather Ford muscle car nacelle astetic.
