No, Im NOT an idiot, the ending was just ridiculous.

Im sorry, but that ending would have made sense had there been ANY foreshadowing of it at all. She spends the movie running from the whispers and then discovers the nature of it all and tries to kill herself to stop that from coming to fruition and then BAM! Apropos of nothing she accepts it? What? Why? What catalyst was there? She realizes she can't change it so she GLADLY (no begrudgingly) accepts it? Most people just get angry and try to kill the people that put them in the situation. The fact that she COULD be saved (as pointed out by others in the movie) means that Molly was Molly and not an unknowing 'demon' in Molly's body. So there's no way to say that she suddenly realized her true place. The whole movie relied on jump scares and not actual tension for the character and the ending was tacked on to make it all seem clever and twisty. It's just a lazy movie with an ending that doesn't fit at all.
