I like them too! The only reason people are recoiling is because they've watched 2 seasons of anime or ~200 chapters of manga and have only seen him without eyes, so I can't blame them for being alarmed
It's very jarring but I liked it more in motion than I did that tiny banner image, so I imagine he'll look much better when he's in motion in the movie and I adapt to this young varsity might
also they picked an ominous fall of fire to show him animated so of course he looks spooky out of context
