Oh, sure, if you want to use redesigns / recastings as indicators of just how little of a shit they clearly give for the source material they're supposedly building on, I'm with you - it's just in and of itself set dressing / costume / makeup is a bit of a nitpick. For example, Enterprise in many ways has better looking sets / costumes / makeup than TOS just as a result of IRL time passing and IRL improvements and expectations.
Like, Klingons now looking like shark people in and of itself isn't necessarily a red flag.
Klingons now being Space-ISIS, and having plans like full body surgical alteration and psychologically constructed artificial personalities in order to better infiltrate their enemies for a sneak attack is just fundamentally at odds with a proud warrior race with an honour based caste system, even though theres that one tribble episode where a klingon is in disguise.
