Sadly, just like Musicaldudepeter, 95% of the population base their entire opinion about a show or an actor's performance on an abridged 3 minute performance on an awards show. Screw the rest of the 2 hour performance of the actual show and/or the actor's actual performance in the show or film, etc.
One perfect example: Tony Pinkins' out-of-context performance of "Lot's Wife" at the Tony Awards from the highly praised CAROLINE, OR CHANGE was simply horrific. So much so, I refrained from seeing the show. I did end-up seeing the show because it was closing (yes, I'm one of those), and was blown away from not just Tonya Pinkins' performance but the entire show itself.
There you have it.
And yes... Kristin Chenoweth rightly deserved that Tony Award. The new number "My Own Philosophy" was just one moment in the Broadway revival of YOU'RE A GOOD MAN, CHARLIE BROWN that she owned on the stage of the Ambassador Theatre. Her scenes with Roger Bart (who, by the way, also one a Tony Award for this performance of Snoopy), were sheer genius. I still laugh when I recall the sequence of her entering the stage shimmying to the Theme of "Hawaii 5-0". One of her many memorable moments in that revival.
