The peace-hair concept is nonsense, of course, given the Klingon kids seen in flashbacks, mirror Voq, et cetera.
I see someone else noticed the de-Botoxing of the lips in a reply to Ricky Spanish, but I haven't seen anyone notice that the image of (who's said to be) L'Rell actually has different ridgework along with softer features overall. Note the area between the eyes and just up, where a V replaces the old shape.
With these changes, the Disco Klingons are going from elongated-skulled hairless half-blind fat-ridged quadri-nostrilled botox-lipped over-toothed jagged-and-gnarly-necked ridge-shouldered beclawed scaly-gnarled-cleavaged double-wanged quasi-race-caricatures that come in various shades of "bruise" to a somewhat smaller set of those traits.
(Unlike T'Kuvma, L'Rell was never half-blinded by brow overhang, but it looks like they're shrinking the forehead along with the lips anyway. Her cheekbones are still built up some and her neck is still hideously gnarly but overall she is now a good couple of steps closer to the proper Klingon look, albeit with many more to go. (Of course, it's a shame Chieffo is hidden at all, but still.))
Now, some are complaining that STD infidels like me just can't be satisfied, often as part of the larger campaigns (e.g. on Twitter) to question our fandom or human worth altogether for not believing CBS hung the moon with this show. That they are changing STD stuff… adding in the classic Klingon ship design, 'painting over' the Discovery uniforms in yellow, and toning down the Klingon make-up… is supposed to allay our concerns at the same time as they show a very different and upscaled Discoprise.
The thing is, that sort of thing only makes it worse. Changing Discovery *
now* only reboots the reboot, as it were, via extensive retconning. Like the original weaponized-canon-policy marketing claim that Discovery was supposed to be Prime, the changes reek of dishonesty as surely as a suspect changing their story under interrogation. All it appears to be is an attempt to muddy the waters by abandoning the previous artistic integrity.
They should've kept on keeping on and just acknowledged the reboot. It would've been the better choice to end the fandom conflicts the nonsensical Prime claim caused, because then everyone could've enjoyed the show on its own merits.
Or, to paraphrase a certain captain, "if we can have honesty, it's easier to overlook mistakes."
