I really, really like it, and am actually suprised with the negative views the changes are receiving. I love the new voice over, and the "You have to escape" or whatever adds so much more to the ride, you're escaping from the Dark Forest, not randomly zooming around.
I really like the new train decor and station, and entrance as well, and I felt it rode amazingly today and yesterday. I initially wanted them to repaint the track, but I reckon it's alright. The track is getting very mossy in some places, and I think that works pretty well.
Basically, if it was an entire new land, and Rita was new with it, it would be awful and pointless. But, they've done the best they could do. I think it fits into the Dark Forest more than it did in Ug Land, but that isn't to say it fits in with the Dark Forest at all. They've done a very good job in my opinion, and I don't think anyone expected much more really..
