It's a lost cause, a relic of a less discerning time. If that show opened brand new today, it would be ridiculed beyond belief. It's nowhere near good enough to justify a 20 year run. Eight foot tall candleabras, foam teacups, community theatre level sets and a ton of canned dialogue/vocals - Disney can do better. While WDW does a fabulous job of keeping a ton of shows running every day, year in and year out, that does not negate the huge lapse of time between updates. 20 years for a stage show, 11 years for a daytime parade, 40 years for a nighttime parade (though not all at this resort).
I hope the replacement show hasn't been postponed or axed - it's very much needed.
