dog the new building style all you like, that kopaka is forgetin bad ass.
The mask looks forgetin poop, it's way too huge and the optical cluster is way spread out more than it needs to and should be. I get that they wanted to change it, and I'm not disappointed that it's not EXACTLY THE SAME (and in fact I'm surprised it contains as many references to the original as it does, considering the sorry state of gali and lewa's masks) but it just looks kind of bad, like someone took one look at the original and tried to draw it from memory. The pieces are all there; the triple-optics, the two head vents, the three holes near the mouth, but they're all assembled in a way that looks really weird. Like a lego uncanny valley.
Still hate the gold armor though, I hope that's just like a bonus piece and that he comes with a white breastplate as well.
I do like Pohatu's mask though, that thing is rad as hell and manages to both homage the original while still taking a new spin on it. The only thing I'd change is make the "cheeks" a bit wider out, but that thing is a solid 8/10.
