At this point, I'd believe we lost a venue we're not thinking of before thinking we'll get 9 mazes plus a tram. It's hard for me to imagine them setting up SS12 this early also, 5 months before the event, when it's a perfectly suitable soundstage. I get film is dead in LA right now and all, but a comeback is on the rise, I can't see them taking it out of commission for that long. When did Bloodlines construction start? To be fair, someone seeing a "maze layout" in SS12 could be very confused with a regular production starting in there. JP and SS12 just feels unlikely. 9 mazes plus Tram is insane...something will not get the attention it deserves.
2019 wasn't the greeeeatest year for me either, even with all those mazes. Us and Killer Klowns were very strong. Holidayz and UCM were good middle tier mazes. Everything else varied on the run through (Creepshow, Stranger Things) or straight up just sucked (HOTC, Ghostbusters, Pandora).
