I don't think the criticism is about the tech being similar to older attractions, it is the fact that the ride looks like a similar experience to a period of Universal attractions which are not very well celebrated in the theme park community. The ride looks a bit flat with too many screens and too few practical effects or show scenes. Big Thunder is nothing new, but it is thrilling, physically present, and features a variety of show scenes with practical effects and the use of projection is used as an enhancement rather than the sole element to be seen.
It might play better in person.
