Avatar made for a better land than movie. I don't think the property is "lousy" so to speak but to each their own. It just feels like some people stubbornly ignore something well done because they don't like it. You can dislike the property but still think they did a good job with the land, which they did. The rides, yeah, I suppose YMMV.
Like many things, I imagine if Pandora were thought up by Imagineers and not an acquired property (gotta stick with the spiel that IP's are bad, right?) that some would be singing a different tune about it. (Some, not everyone). But then on the other hand, there are people who completely dismiss AK as is, regardless of the nice theming it has, so .... I really do think some stubbornly won't admit a job (mostly) well done because of some intense dislike for certain things. Look at Ford, he's made himself so disgusted by Disney that he refuses to like or acknowledge anything they do. I can separate the two. I can separate emotion from what I perceive something to be well done. (The Pandora boat ride IS well done, it's just short and slightly lacking. What's there is immersive and IMO, well done. Sorry some of you need a story spelled out for you). Just like arguing against Toy Story and it's scale. Sometimes it's really NOT that serious but that's what we do, debate and pick apart everything because we're superfans. (And while no, Toy Story doesn't necessarily lend itself to immersion, but why let yourself dislike it because of some other issue you have? It's harmless. I can understand some gripes but I just don't get the hate. Would I prefer something else? Would I do other things? Sure. But it doesn't make me hate what's coming).
