I completely agree with that¡ And we love to see Jack in all his beauty,mainly when he feels sad and vulnerable,because he's more charming then...
Charming, yes! But he can also be very deep/profound/moving in those scenes, without meaning to -- at least intentionally!
But especially charming are those scenes where we see him almost like a little kid -- as someone without guile. He is so lovable in those moments. He reminds us of a certain untouched innocence.
