At Broadway prices, people have to leave feeling that they've sat through something worthwhile, even if it wasn't. Perhaps the standing ovation is for themselves.
"Well, it was only okay...but everyone learned their lines and knew their blocking and was committed to this EXPERIENCE...so we might as well stand and applaud their and our commitment to the EXPERIENCE, which cost me some high bucks...well, that's New York!"
It can, I acknowledge, be an ambivalent experience when you are "feh" on a show, but admiring a performer's gusto and skill. I recently had this experience with BAM's less-than-invigorating THE TROJAN WOMEN (AFTER EURIPIDES). Ellen Lauren poured her guts and power into a challenging role and soared, but the rest of the cast was weak and the production's ideas puny, in my opinion. The cast came out to bow and I remained seated. Then she came out to do an a sola bow and I stood. Sucker! She threw her arms out and the whole cast gathered around her for "her" final bow. Generous, yes, but let the audience give high credit where high credit is due.
It sounds to me like the audiences of SCANDALOUS and CHAPLIN were standing prematurely for their respective stars who, by all reports, were working their asses off. Also, is this strictly a musical phenomenon, do you think?
Generally I find the immediate standing ovation less of an issue off- and off-off Broadway.
"Impossible is just a big word thrown around by small men who find it easier to live in the world they've been given than to explore the power they have to change it. Impossible is not a fact. It's an opinion. Impossible is not a declaration. It's a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.”
