I think it would be better for you if you untangle those 2 things in your mind. I think it's clouding your judgement and making you unable to take things on their merits.
Reality is; Rivals is a really good coaster and is probably one of the biggest things that has helped Movie World get out of the post accident slump. As for 2 years and still getting praise; yeah what of it? It and Superman are really friggen good. No one heaps praise on Doomsday or Batwing because they're filler.
Mostly what Ardent has added is also filler. DW got praised for the better part of 2 decades for the Tot/GD combo too, and with good reason. But they never followed it up with anything else amazing, and now those rides have been surpassed, it's very 'The king has no clothes' sort of thing.
Reality is; Sky Voyager will probably be pretty good when it opens but it isn't yet. DW also bet a lot on that ride giving them a boost. The ride isn't open and they haven't had that boost. If you want to pretend that the reason it isn't open yet is because they were doing something so innovative, new and ambitious that it was impossible to get it done on time then that's up to you. You could face the reality and admit the truth that the ride is delayed because they are caught in a world of regulatory hurt that they caused themselves by falsifying documents to OH&S before TRRR's accident, but again, you should not be forced to allow reality into your bubble.
Finally, you brought up Rivals and Sky Voyager in the uniqueness thread, so here it is, neither of these rides are unique. Rivals is excellent, Sky Voyager will probably be very good when it opens, but neither are unique. If you think Sky Voyager is unique because of a custom film or by virtue of the fact there's no other simulator like it in Austrlia, then Rivals is also unique by virtue of custom layout and being the only coaster of its type in Australia. You can't have one without the other.
