This is a totally valid viewpoint. However it didn't work for me like that.
The Breen worked well as a sudden mystery enemy on DS9. And it was nice to have an alien species not looking like all the other ones, having a unique visual twist & identity with their suits. For us to have some nice speculation what they really looked like, why they wrote their suits etc.
However that was what, 25 years ago? For new fans it's meaningless - they don't even knew about the mystery in the first place, and they got the solution first. And for old fans it's most likely not fitting with any old theories. The explanation for their suits (the two faces) is actually not too bad, I kinda like it. But I don't like the look of the make-up itself.
I think it's mainly because my biggest gripe with modern Trek had always been that it tries to be more of a gap filler for 90s Trek, instead of just throwing it's own ideas on the screen. And even if they have new ideas (like here), they always try to connect it to previous canon, even if it doesn't really make a lot of sense. I would have loved an Orion background character. But Orions being the main antagonists 1000 years in the future? Well that's boring. The return of the Breen was certainly handled better. But again, they missed their chance to make their own mark, and introduce their own, cool new aliens to the franchise. Instead they just crafted their idea onto an existing hole on the franchise, kinda' devaluing both.
