I too would love a sequel to Interstellar Terror. House that related to my fear of plane crashes (aviation disaster), which is one of my worst fears. The house made you want to get out ASAP, so the conga line actually HELPED make it scarier. So many cool effects: the exploding hallway, the electrocution, guy getting sucked out, mirror gorge, Roddy as captain ("I CARVED THESE INTO MY FACE!").
IT was such a criminally underrated house--it created a true sense of panic. Similar to Dinosaur, which isn't a very well-liked ride (honestly, despite how everyone talks about how they neutered it from its CTE form, Dr. Seeker's monologue was MUCH less urgent when it was CTE--so in at least one way, they actually made it more intense).
My idea is for a crossover with In-Between at 30, though I think if they bring back In-Between they'll want to make it as cheap as possible IF the 13 houses for 30 rumor is true, and IT would likely make that too expensive.
