I agree with Channing and John. I have no idea who Chris Evans and Kenneth Parcell are, but suspect I'd agree with you there, too!
No celeb does it for me, though they're of varying levels of attractiveness of course. The only one who was a "why are people into him?" that I'm starting to see is Adam Levine because of his personality on The Voice. When a famous and rich guy who has has a pretty easy life (at least publicly) chokes up while talking to someone he barely knows about the fact she was bullied, his empathy makes him far more attractive than he was before.
