I loved Bindy and didn't have any issues with its ending, but I don't think I loved it because of the conspiracy, which leads me to conclude that a decent conspiracy-less ending would have worked just fine.

It could still leave some, albeit much less dramatic, potential for friendships to be made through trying to save Bindy's life, too -- she's still being poisoned by her father's toxicity and her own unhealthy ideas about the world and also the wallpaper (or whatever it was in the house).
