I think the former - the boxes are pretty big and ugly attached to the train - but they did light up the more vibrations / noise there was.
Agree with what Ryan said, it’s important to remember this coaster is X, a couple of the block sections have been re-programmed to sync up with the theming but other than that the ride it’s self is the same.
I’ve always found X pretty fun, even back to X:\ No way Out days, and again this is a fun experience, there’s a complete story throughout and the theming is good, especially in the queue / exit area, really like the amount of Easter eggs too with throw backs to old members of staff, old advertising for X:\ No way out etc. I think it will do pretty well for the park but time will tell!
