NRJ...what can I say, I understand why people like it....they achieved what they set out to do with it from what I can tell. It's part of the overall mood they're trying to convey with the rest of the land, and using the latest in digital and lighting effects.
It did remind me of Journey to the Center of the Earth in DisneySea which I know most of you haven't been on, but on that ride, it's just the beginning of the experience and a lot more things happen.
NRJ is about 1-2 minutes too short overall, I think everyone can agree with that, and one amazing animatronic doesn't alone make it a great ride. Speaking of which, how many actual animatronics are in the entire Pandora area? I know the first Na'vi you see in the ride is NOT an animatronic but a clever lighting effect.
