I would be fine with a few performances that strongly referenced the video. But not all of them should be doing that. And they DEFINITELY should not be doing that when you've done it tour after tour after tour. If, RN and others are very iconic so it's very risky to toss out the original choreography in favor of something brand new (esp. when some people will be seeing Janet live for the first time) but if J found a way to have themes throughout her show things might work out. Maybe she can have snapshots of the classic moves injected into new routines.
This thread alone could revive this woman's career. Let me see what she gives come tour time. I'll be here bytchin up a storm if she does the same ole show but with Feedback, RWU & Luv. lol
