I think much more the other way, based on setting, Marvel/DC and that's really what we're talking about here is about as far removed from Tolkien et al as its possible to be. Superhero is plastic genre, so shallow and superficial, full of sound and fury signifying nothing. There's no weight to it at all, a few flimsy repetitive cobbled toegther back stories, which change at a whim to accomodate more of the same, whereas I think "classic" fantasy has historical heft even though it's entirely fictional.
So from a setting, lore, world-building and "historical" flavour viewpoint, I wouldn't place this rubbish anywhere near fantasy, it's not worthy of being the same conversation as the best of fantasy or science-fiction. An entirely inferior genre.
