TMP was a sequel that came after the events of TOS. They gave a reasonable explanation why the Enterprise looks different. It's not the same thing. That's an easier pill to swallow than a prequel that looks more advance than the show it's supposed to be a prequel to and we're just told to deal with it. I know it's not 1966 anymore. And I'm not asking for it to be 1966 anymore. All I ask for is a little consistancy. The exterior of the connie is fine. Yeah the interior looks cheap because back in 1966 it was made with cheap materials. Should they ever update the interior and it looks like this.
Then I would be okay with it because that's an update done right that doesn't completely change what is established. Now I don't mind what the Defiant looks like in Episode 10 because I know what happened to it. And that's an update I can understand because it's been in the MU for 100+ years. Now if and when the Discovery returns to the right universe and the constitution looks like the MU Defiant, I at least hope the Saucer is smooth without those 2 bevels. I'm fine with the pylons as they are mostly unchanged. I'm not a huge stickler of this kind of thing but as someone who suffers from OCD it is a bit annoying and I understand it. I might not always agree to it but some things I can be more open to than others.
