I've been here before as a creative, so it gives me no joy to say this, but Triplets feels like a case where the team got so invested in their "big idea" concept that they eventually got lost deep in the woods instead of seeing the forest for the trees. It's a cool idea on paper, but the story just doesn't translate in practice, at least in this form.
I think this is a house that really would have benefitted from some "play testing" // "test screenings" during the later stages of development. I fully understand why they don't typically do that sort of thing, but they needed some perspectives from people unfamiliar with the nuances of the concept. I imagine many would express confusion if they were presented the current layout/progression of events without any prior context or setup, which would've given the design teams time to make crucial adjustments. Everyone involved with making approvals here was "in too deep" to realize their premise had become incomprehensible.
