Agreed. To me, this ability to be a chameleon is a remarkable quality in one so young, as it is usually a trait of a seasoned artist, who can morph him/herself into many different roles convincingly (Michelle Kwan was brilliant at this). I think Brown is a more mature artist/performer than Hanyu, especially with Hanyu's programs this year -- he seems a little disconnected from the audience, the music, the performance. But this may well be related to his attempting such difficult technical content and being preoccupied with and exhausted by it.
In fact, Jason's coach said in interviews that one reason they decided to exclude the 3A so far is so that Jason can focus on the performance/PCS aspect.
