Approaching this as objectively as possible, i think something that makes a GREAT Horror Nights IP adaptation is how they often put YOU in the shoes of the character and put YOU in the scenarios those characters faced. In other words, YOU ARE Joel and Ellie and YOU are witnessing what they witnessed; The horror/terror impetus is thrust upon you to get through the house like those characters got through those scenes. Compare this to a storybook/narrative IP adaptation, where it feels more like you're watching recreation of scenes between characters, where you're NOT the character, and instead a passive viewer of the story as it unfolds. The best comparisons i've got are how it felt like YOU were in the apocalypse looking for Rick/Daryl/Michonne in the Walking Dead Houses and they didn't often have anyone PLAYING any of those characters because the implication is that they want you to FEEL like those characters or how you felt like the Maitlands being led through Death/Afterlife and meeting Beetlejuice in the Beetlejuice house and how you were put behind the driver's seat to feel how they felt interacting with those characters, imo. Put this against the Ash vs. Evil Dead or Stranger Things houses where you're literally seeing Ash fighting deadites or Eleven/Max fighting Vecna; You're NOT the character in these situations, but in their universe, recreating those scenes you've once watched.
TL;DR: PERSPECTIVE.
Follow me here, cause i -more or less- felt this way when they adapted Last of Us the first time, and i witnessed this exact difference between the two houses on each coast that year. In Hollywood, they had Joel and Ellie actors in almost every scene, you were constantly seeing them shoot at something or run from something or what have you and instead you were a witness/bystander to their engagement with their surroundings. But compare this to Florida's where there weren't any actors for Joel and Ellie and instead YOU were meant to feel like Joel and Ellie going through those situations. It was an entirely different experience from coast to coast but it was the same property, so it was wild to me that they'd have such drastically different adaptative perspectives. In a weird way, i think THIS IS the simple solution. To just... do the same thing they did last time. In Florida, we will likely be having their(probably Ellie's) experience watching things unfold from her perspective and i would not be surprised at all if California does the same thing they did last time, which is the opposite, and cast multiple actors to play multiple characters and you're instead seeing recreation of specific scenes.
