The Biggest Plot Hole (That Ruined The Movie)
When the daughter finds the box about Diana and plays the tape, the FIRST THING the doctor says is that Diana has a skin condition that makes her extremely sensitive to light.
........SO WHY IN THE WORLD WOULD YOU GIVE A PATIENT LIKE THAT *LIGHT* THERAPY??!!!
I mean we're talking about someone for whom even a small amount of a light is apparently deadly, let alone HIGH INTENSITY, FULL SPECTRUM LIGHT. And I paused the little article she picked up, light therapy (which is a real thing apparently) is for people who are bipolar & whatnot, not for LIGHT SENSITIVE skin conditions.
I mean it is literally the equivalent of trying cure somebody's allergy to shellfish by feeding them a *beep* of shellfish.
After this happened it pissed me off so much I could barely take the rest of the movie seriously (not that there was much to take seriously to begin with).
