I'm watching Lucifer as we speak, and I thought to myself... every main character in this show is extremely good looking, too good looking in fact. The only one who couldn't pass for a model is the therapist. I know sex sells, but I don't know a cop or detective that look like Lucifer or his crush Chloe. Not even close.
Comedy doesn't count lol. My favorite show is It's Always Sunny, and yes, none of those characters are described as sexy. I watch it to laugh, and that's it. Most comedians become so funny because they're not usually good looking to begin with. If it was a drama that involved some sex, would you still wanna watch if it wasn't beautiful people?
