That's an opinion many would disagree with, and they really improved it in DSC Season 2.
Ooof, hard disagree. They tried to unfuck it in Season 2 by adding TNG/DS9/Voyager elements to it, but not letting go of additional lousy aspects. The clawed hands, the weird purple skin, the strange necks, the 4 nostril noses, the puffy cheekbones and chins.
And then they finally introduced the D-7, 90% the way to a K'tinga, which is great, and put the awful Season 1 ship design behind them.
I'm not an adversary to change to visual canon whatsoever. I entirely bought the different look of Starfleet in Discovery Season 1 and 2. I'm very cool with the Discoprise (though I wish it had straight pylons). The Picard Season 1 Borg redesign I was fine with. The changes to Tellarites and Andorians have been perfectly acceptable.
I don't like the Klingon redesign because it's not a good alien design, period. It looks like an expensive bad Voyager alien-of-the-week. I think i'd like it more if they gave them typical Klingon skintones, rather than the extremely weird purple, grey, blue and slate black ones they gave, and normal hands. It's just layers of crappy change on crappy change.
As I said before, this show spent 2 seasons getting away from Bryan Fuller's mishandling of it and the mess of development ideas about "what the next Trek show would be" that pre-dated Season 1. Going to the 32nd century saved the show and I deeply enjoy Discovery now. I hope SNW does the 2250s with much more finesse now that Star Trek seemingly has found its own two feet again. But as much as I enjoyed parts of Season 1 and Season 2 of Discovery, i put the Klingon design, and many other aspects of the, firmly into the "we're a new production crew figuring out Star Trek", which is, to be fair, pretty much exactly why TNG Season 1 and 2 were uneven. Gene brought back some vets, but it was a lot of new people behind the scenes, figuring out what Star Trek was and (along with Gene) not really wanted to be tethered to what came before.
