Well I agree with most of the people on your list...except maybe Amanda Seyfried. She's not really "hot" in the conventional sense, but she's in the same category as Natalie Portman. She has that classy/feminine look. Most people on your list are definitely not ugly, just wayyyyy overrated being that most are average-looking. Robert Pattinson somehow became no longer stunning after his Harry Potter character, Cedric Diggory. CD was smoking hot. I don't know what happened to him. Did not dig his look in Twilight. >_<
I would like to add some people to the list:
Stella Maxwell (without makeup or with little makeup...very average face, but nice body. I think the problem is that she has a weak/short chin. I just prefer dainty feminine faces like Elsa Hosk or Taylor Hill)
Eva Mendes (masculine/rough face)
Kate Beckinsale (pleasant face, but I don't really see the extra appeal...)
The guys from Five Seconds of Summer (guess it's my lack of teenage hormones)
The guys from One Direction (same reason as the above)
