Decent, feels unfinished though.

Apparently people don't know why lots of fans didn't like the look of the Discovery Klingons?

I'll explain as one such person - it was another symptom of the writers not giving any respect or care to the work of those who had written the lore before them, even though they were standing on their shoulders, to the point of malice.

Klingons evolved on an M-class planet of caves, with icy mountain tops housing homes and monasteries, a thick atmostphere, and both cold and warm cave systems - some volcanic, but erupting rarely (~centuries). They had evolved with hair and grew it long to provide warmth, with long hair and well-kempt facial hair (beards, mustaches, large eyebrowa) being common and distinguishing features, along with their head ridges.

The initial Klingons of TOS had no facial ridges, and ENT went to lengths to work an explanation into the lore that they had made a genetic virus to eliminate humans during their first war (or something similar) and it backfired, Phlox was able to help them with a cure, which allowed their head ridges to return. To me, this is the kind of story that someone who appreciates and respects the writers before them and the fans dedicated to the show, would attempt.

Do people not remember that Discovery started out with completely hairless Klingons - no explanation? Until there's a fan backlash and complaints about season 1.. And then they magically have it back for season 2 in specific episodes, with the backpedal 'oh, they shave it during war'. The now also have wide, flared noses - which given they are mostly black-skinned in season 1, though their actors are mostly not felt frankly pretty borderline cringe race-trope imo.. Overall their features are generally really smooth now, like some kind of fish-people that evolved on an aquatic planet.

Discovery writers really seem to hate Klingons to be honest: they blow up parts of their planet in The Burn to kill most of them and make it inhabitable, reducing a proud species of intelligent warriors that have previously brought fear and respect wherever they travel to a sombre group of refugees from a race on the brink of extinction. Then again, in the mirror universe they also destroy Kronos by blowing it up - but properly this time. Disintegrated. Then later in Picard, they wipe out the entire planet's population with a biovirus... I really don't see any other conclusion than someone on the Kurtzman crew hates Klingons (or their fans for speaking out about dumb lore changes, or both).
