I think that a real fireball from “outside” would help sell the destruction, but I understand given the tightness of that space and what’s in it why there isn’t one. I can’t think of any attraction with real fire that is *that* close to the guests or animatronics.
I’ve been avoiding videos until I can get on it for real, but is there a blast of fog or is it all projections and the falling ceiling? If the latter, perhaps real fog or LN2 would help mask the slowness a bit.
