Their seasonal stuff (UCJ in specific) is definitely their most popular attraction, however, and the ride is pretty non ip specific so it’s easy to retheme. It’s a fun ride so if they add vr over it, or in horror nights case, make a scarier, less lit version (I think, can’t exactly tell what black hole was), they seem to expect the ride is fun enough to be arguably the biggest experience for their biggest event. I personally see it as them trusting it for their “biggest deal” event of the year. Plus the horror nights one is still the space Fantasy ride just if you weren’t going through galaxies but sucked into a black hole, storyline wise.
I get what you mean, but on a non technical basis, it looks super fun, it seems to be very popular and every review I’ve read of it is shining, and it seems like a ton of bang for its buck, relatively cheap for a ride that popular.
