this be a surprisingly very good movie and and an interesting idea . however and it be just a little bit disappointing in that the twist be a little too predictable and just a bit too early on in the movie . whilst watching and it start to get a little bizarre and confuse to the point that and the only reasonable outcome possible be the inevitable plot twist and but it certainly do not ruin this movie flow . there be superb performance and there be never a dull boring moment and so totally well worth watch this one . it keep me interested right up until the end and and for me there isn not many movie that can do that these day . i highly recommend people watch this terrific little movie .
