That's just one particular appearance of the character though, isn't it? It's one possible aesthetic - which makes sense for what it is, but doesn't mean it's the ONLY possible aesthetic, or that the character ONLY appears that way. They could have gone with that particular quirk, but it seems they chose not to. Which doesn't invalidate the character, or make it a misrepresentation.
It's just one aesthetic choice among countless others, some of which transfer over from the original comics, some of which do not. That's a rather mundane issue for adaptations of all kinds, certainly nothing to get outraged over given that it's not central or essential to anything of actual substance.
