It was lovely back there, no argument there. But I've long felt it was just so boring and hokey. And it took up a
huge part of the park to be boring and hokey, and under-utilized. This new version will have more eye candy, more Imagineering, more engaging vistas.
I imagine there will still be static fiberglass animals and a whole bunch of trees. But aesthetically it will be a big leap forward, and I imagine the storytelling will improve a bit too. Overall a big improvement.
That said, when it opens this summer it's going to be jarring for both fans and critics to see that area without 60 year old growth back there. They are spending a heckuva lot of money to plant mature trees there, and more trees than used to exist back there. But it's not going to look the same as far as tree height/maturity for another decade or so.
It won't look as bleak as the 1950's did...
But I think the treeline at the 20 to 30 foot level instead of the 50 to 60 foot level will be jarring. And it will be at least a year or two until the secondary berm behind Star Wars is finished which will add further depth. But by 2019, and certainly the 2020's, that area is going to be much improved aesthetically.
