If Cillian Murphy is “ugly” then what does that even mean?

I see people calling him ugly andimoto is what the majority of people call him. He has a face of a classic hollywood star - nearly symmetrical and chiscelled features. His face is very alike Mads Mikkelsen’s. I really can’t believe what I’ve read, his face is more “pretty” than mine will ever be. You can hate people for no reason but he’s not aesthetically ugly.
