Original premise, solid acting and a great ending. The actors were largely unknown here in the US, but they did an excellent job establishing the characters and progressing the story. Directing was also solid. The scenes were well developed and the shots were dark and creepy, which helped build tension and suspense as the movie progressed. This is horror that is psychological enough and creepy enough to appeal to horror junkies and drama fans alike. The ending was great and wrapped everything up perfectly. I thought the story was also very original but with parts that harkened back to the best stuff in the 70's and 80's. It is a must see but be careful, it will suck you in so enjoy.
