I love how amazingly similar our ideas for a Cornetto Trilogy maze is! I almost wrote a treatment on the HNNightmares forums of that, which starts off at an 50's-inspired Drive-In Theater (as a nod to Baby Driver).
Is it odd that I could see S1+S2 being only at HHN, but The Return only at KSF (if they were ever to do an IP maze again)? The whole difference in vibes between the two eras fits perfectly with the vibes of the corresponding haunts/theme parks to me.
While I wouldn't want a Cornetto trilogy maze... Edgar Wright does have a vivid imagination...
And eh, I wouldn't like to see KSF touch Twin Peaks. Again it irks me Murdy hasn't bothered thinking about it, there's so much he could play around with, but I feel it would have to be FX heavy. Season 3 is fill with content as is Fire Walk with Me. Seasons 1+2 have a good amount of stuff as well. It maddens me that we'll probably never get Twin Peaks due to Murdy's neglect of the show.
