The actress looks cool and I’m sure she’ll be fun, but I do like the original Domino design and think it would have worked better onscreen. The X properties have gone out of the way to normalize most character designs, but when they didn’t like with Mystique, Nightcrawler and Beast those characters were stand outs. I think in almost every situation the original character design is the best one. There’s a reason it’s worked so well in the comics.
It’s a shame that we had so maybe Jackman movies and never got a proper Wolverine in costume sequence.
