Evans was among the most charming, in both acts his inherent boyishness just a complete revention of the role, which (in my mind) had the Patinkin stamp on it prior, no matter which actor I saw I saw.
And now Gyllenhaal has gone in another direction. He has the such pain, his inability to look up from his sketch pad is just achingly sad. But he's also the most believable at the start of act two as this socially skilled George of the art world. He finds a lighter touch for "Putting it Together." And of course, he has that charisma thing. Evans was almost child-like in act two (winningly so, the role stretches thus). Jake is -- well, like a movie star. It works in act two.
