I found this movie really amazing. Each character had their own story, whether it was shown or not. Every actor in it was really into their role, like all of them had experienced something like that before.
I watched this movie think it was going to be a sci-fi movie from the title. I tend not to read much about something and just watch it. I'm actually glad it wasn't. It had a nice psychological feel to it and I would definitely watch it again.
