But are they? They are still identifiable as Batman ears. It's not like he has antennae on his head - it's just a different style that we've never seen on film before and it gives Batman a much more devilish, creepy silhouette which, again, is fresh.
This cowl is already more removed from Affleck than Affleck was to Bale, simply because it's a leather mask now instead of a sculpted rubber one-piece which is a welcome change. But the ears are the most prominent aspect of the cowl that will differentiate Rob from everybody else. We've seen them long, we've seen them short and we've seen medium length all in style of the traditional straight ears but we've never seen the '39 style.
And angled ears are in no way comparable to Batman wearing a tutu, come on now.
