They could update the attraction, like replace the huge oval moniter with an updated screen from the 3rd film (via hologram from Potter and Disaster!), display the new Ford Taurus MIB cruiser up front and for the songs about switching between 3 movie soundtracks like
Pitbull's "Back in Time" along with Danny Elfmen MIB scores. The ride should remain the same.
Or as Boris the Animal would say...Let's agree to disagree.
