I'm still up on the Triplets themselves, but the house didn't meet the personal hype I had. Going through, it gets SO CLOSE, I just wish it was longer and carried a climax.
My personal dream sequel would be a prequel - I would love to see a house earlier in the timeline where they suck at murdering/make mistakes. Something like this would only work with having already had the house we have now, and would elevate it conceptually imo
