Why concept art must be allways better than actual movie
Well, it's more stylish, but I wouldn't necessarily say that most things we've seen in this project's concept art would've been better
on the big screen.
Different, but not unquestionably better.
With that said, it would've been nice to have seen the partial crustacean themes kept for the trilobite design, as seen on these. But, again, it wouldn't have been a really massive improvement (and the old superfacehugger design, minus the leg membranes, would have been better than any of them).
