I, for one, like the old helmet style that LEGO used in "Age Of Ultron," because of the fact that the helmet is actually movie-like. The new helmet...eh,...not so much.
But I also think that the helmet is usefull for some things, like "Spiderm: Homecoming" vulture helmet. Oh, and also the MARK I and MARK II ironman helmets also fit with these designs. So does MARK LI, but not the other ones, especially not MARK LXXXV.
