What is it about JG? How much time ya got?
From an old fans pov tho, I'd say looks gets ya first, talent & then that boyish goofiness he exudes from time to time. Not to mention he's rather intelligent in an unassuming way.
All in all, not unlike the kid next door .( I wish ; )
As for the comparison to Monty, I'll pass on that one. Just don't see it. MC had a sort of nervous energy in almost everything he did. Jake on the other hand, a quiet kind of force.
Theres a scene in Jarhead that grabs me every time. See it & you'll know the one.
