I don't really want to give a full review. Not really any spoilers below. Just an overall impression.
The land is pretty, but it's all rocks, trees and water falls.
Honestly there's not much to do there. The two rides, a gift shop, and the canteen. It's all located along the far wall close together. Everything else is walking paths. I was expecting cool details and surprises that we didn't know about while walking around but there's not really anything there. Most of the land is unused space with pretty trees and rocks.
The river journey is really detailed. It's mostly projections with 1 AA that is incredible. The ride is really really short. The people that wait 2 hours to ride it are going to be MAD. There are only 4-5 rooms in it but the boat moves slow so you think it's longer.
All of the money in the land was spent on the Flight of Passage standby queue. It seems like a mile long and it's room after room of amazing detail. If you go in the Fastpass line you don't see any of it. FOP was cool. It was NOT ground breaking but an evolutionary step forward from Soarin'.
The gift shop was a gift shop, the canteen looked like something in Animal Kingdom lodge. Food was above average.
That's the entire land. You can see where all of the ground is painted with glow in the dark paint for the night time.
My big complaint is you could see the light fixtures on the ground and mounted on rocks and trees for the night time light up stuff. They don't try to hid any of it at all. Even inside the queues and rides I kept noticing led light strips everywhere. Maybe I'm just being over critical but that stood out to me.
All in all the land is an A+ but a lot of it is wasted space with nothing to do.
