Star Trek hasn't born more than a passing resemblance to "The Cage" since at least TMP. It's LONG since moved on from trying to re-capture that style.
In fact, with Star Trek already being well over fifty years old, expecting it to in any way start mimicking its styles in the 60s or even in the mid 70s would be an exercise in extreme futility. It would be like going to an apple store and asking "What's the modern equivalent of the Apple IIe?" and then getting mad when they show you an iMac.
I don't see how. The overall style and look still fits. It's just that you're looking at the equivalent of FIFTY SEASONS of development, which is a pretty radical change.
The only other real comparison would actually be something with similar longevity like, say, Doctor Who.
There's the Tardis:
And then there's the Tardis:
^ And this one is far closer to the ORIGINAL aesthetic than any of its previous incarnations.
Just saying: You can nod to the originals in various ways, but you can't just run back to what came before as if nothing new should ever exist. That would be boring as hell.
Directly and explicitly copied TOS styles, costumes and prop designs in an episode whose entire premise was sold on the fanbase's nostalgia? That's good for an episode or two (Doctor Who also does this occasionally; no TV show that's on the air as long as either of these can avoid it), but you can't build a whole TV series on nostalgia.
Well, scratch that... you obviously CAN. That doesn't mean you SHOULD.
