Bad Show is a Cast Member talking on a cell phone while leaning on a rail and yelling to other Cast Members.
Construction, and reimagineering visible to Guests is an exciting and promising look at what's to come.
Just listen to Tony Baxter or John Lasseter when they talk about peeking behind construction walls, preview centers, and how excited they are about making the construction at DCA something not hidden or encumbered.
In fact, the reluctance to let the public in on exciting additions Pre-2006 have kept us from getting new expansions, and new attractions at WDW.
I'm a firm believer in "Lowering the walls" and letting the work be done very publicly, it drives interest.
