In a park dedicated to the environment, ecosystems, and conservation...a relaxing river cruise through an alien planet that heavily relies on the ecosystem working together seems like the perfect addition to the park. Not everything needs a thrill or a "something goes wrong" or even a story that is laid out and explained perfectly. If the ride didn't have the huge wait times and was just a secondary attraction to ride (like Gran Fiesta Tour), it would be great. The only downside to the attraction is the lack of animatronics and how all of the creatures are screen-based. That is a huge miss IMO.
I do agree, however, that the land is lacking. To make it feel more cohesive to the other lands, a walkthrough "safari" type of attraction that starts off as part of a museum that explains the war and focuses on the Na'Vi culture and then you leave the military building and complete your walk seeing animatronic creatures (maybe have an interactive photo-op like Universal does with the Raptor), have some interactive flora and maybe have a small area with the glowing footprints as you leave.
