Why is Robert Pattinson so popular?

He isn't that talented of an actor, his roles until Twilight have been minimal, he has average looks and no build to speak of; so why are so many women infatuated with him? He is a product of Hollywood plain and simple. You take any average guy and give him a "star quality make-over" and they will lookthe same or better than this drone! His acting skills are minimal at best and why are he and Zack Efron allowed to present Oscars?
