I had hopes for this movie but the story seemed to be written just so Sara can act in a movie. There are just a couple of things in that movie which were good ideas, like the last killing. Overall it is 'not a good mystery' and it does not make any logical sense when things are revealed. As a viewer it seems like you are forced to admire the heroine when the truth comes out which actually feels like bad writing as it is so on the face and isn't done subtly at all. Overall, it feels quite lazily made and doesn't even justify the title. Actually the lantern seemed to be not even a gas one, may be it was electric, but that feels quite deceiving and pretentious then, like the entire movie.
