Gone [Celluloid Hero]
When a movie sets off to be a thriller full of twists and turns, the biggest problem it can face is going too far. Unexpected moments are great, but when it starts to feel like they were created for the sake of being unexpected, rather than genuine surprise, the movie can suffer.
"Gone" follows Jill (Amanda Seyfried), a young woman who was abducted a year ago, but managed to escape her attacker. The problem is, when the police investigate her story, no evidence turns up. All signs point to the event being a figment of Jill's imagination, but she refuses to back down and constantly tries to find the man she believes kidnapped her.
Jill's younger sister goes missing, setting the main events of the movie into motion. Jill frantically searches across an entire city, getting clues from random people, creating fake stories to gain their trust, piecing the puzzle together. The police still don't believe her, and some of her actions result in them going after her instead of the imagined/real villain.
Spoilers are always avoided here, so there is a huge plot point that I won't get into. The problem is, that very plot point is what changed my entire view of the movie. I'll just say that the viewer is given two options: (1) Jill is telling the truth or (2) it's all in her head. We're presented with evidence to support both, and I will say that a definitive answer is given, there's no room for interpretation.
