I think cornrows look pretty nice on some people. It depends on if they look good with hair pulled back and away from the face. Like, if they have the kind of face and scalp to be flattering with that look. I also don't like super elaborate styles/designs in cornrows, personally. I like simpler looking cornrows.
Cornrows look good on some people, so it's not for everyone. The way the conrows looks is very much dependent on the shape of one's face and their scalp......it can either be flattering or not good at all. I think that simple cornrows look good, and should not be elaborate.
