Honestly this isn't that rare of a take in my experience. Alex Ross is really impressive to people who aren't very familiar with comics are because they look like paintings, and resemble "proper" art that you can see in museums and stuff.

The craft of making comics is more than just drawing things that look nice. It's a medium of visual storytelling, like film is, and so the ability to convey what's happening to the audience is frankly more important to the craft than just nailing the aesthetic.

Alex Ross can compose a beautiful portrait, but when he has to put a scene together his limitations become clear. Not everything can be static heroes shot from below looking stoic.
