Excellent. The blending of screens and sets is by far the best we have seen. Its hard to tell in some place because the have 3d effect screens where the screens and sets are layered on top of each other so you'll have a translucent screen on top of a set on top of another screen. The Navi shaman is massive too and you get right up next to her. Dont expect a blockbuster e-ticket just a nice relaxing river cruise with a good (and catchy) soundtrack while enjoying the sights and you will not be disappointed.
