I don't see it as a prequel the way ENT was one. It's an updating and fleshing out of the time
Of course it's not a prequel the same way, because it's a different show. But it is a still a prequel by definition -- a subsequent installment in a continuity that's set at an earlier time. (Okay, it's not a prequel to "The Cage," but it's a prequel to the rest of TOS.)
I liked how Spock had a different collar to account for his longer neck.
That actually had something to do with keeping his Vulcan makeup intact, or keeping it from smearing the uniform. (Or maybe to keep the edge of the makeup from showing under the collar?) They did the same thing early in TOS -- Spock originally had a higher collar than everyone else.
I don't think of it as a prequel. A prequel has to fit into continuity, both past and future. This show will honor continuity to an extent, but it will mix, match, and rearrange it as they see fit creating an entirely new reality going forward. Harry Mudd is an example.
That is simply false. The producers have stated over and over again that this show is set in Prime continuity and will stay consistent with it, and I've been assured of the same by my friend David Mack, who's read the scripts, and my friend Kirsten Beyer, who's participating in
writing the scripts. They're not contradicting Trek canon (at least, no worse than Trek canon already contradicts itself), they're just filling in its gaps in unexpected ways, just as
Enterprise did. If ENT was the
Star Wars prequels, DSC is
Rogue One and/or the Han Solo movie.
And really, how is Harry Mudd an example, based on the few seconds we've seen of him? Because Rainn Wilson is much older than Roger C. Carmel? Well, most people assume Harry Mudd was middle-aged anyway even though Carmel was younger than Shatner. Because he has a beard? Big deal, people can shave.
