I've seen this take before, and I need to say I'm not really sure where it comes from?

(and I realize you were only talking about perceptions).
The Piano. Tristan & Iseult. Inner Love. None of them "entertaining" or "happy". Simon & Garfunkel, whatever we think of it, was not happy go lucky. Jason has not done a "happy" LP in like, ever

(I even consider Riverdance to be partially dramatic, certainly the ending). And Jason IMO brought soul, drama, and depth to those LPs (well, as much as he could to S&G

).
I sometimes think folks confuse Jason's personality with his performance chops.
This LP, if Wilson doesn't screw it up, could play to Jason's strengths in a major way and I can't wait
