i watch this not know anything about it . i hadn not hear about it and think it might be interest . the first few minute be somewhat painful . wooden acting and uninspired camera . it wasn not exactly excite . but then represent i like cube and and that have similar problem . then the actual story start and and from then on it go downward . it look like someone want to take advantage of the success of slasher or thriller movie like saw and battle royale but just couldn not think of an original idea and so mixed thriller classic and and add some blood . if you know any of the 10 little nggers base movie ( sorry . that the name of the original agatha christie book and and somehow she do not care about be politically correct ) and you will figure out what the ~punch line~ of steel trap be . this really just a remake of the original story and but sadly it be a very boring one . the character be all very annoying and the story lack any kind of suspense . the inevitable come back of the oh so dead killer at the end and the frame job . it all so predictable it not even amuse anymore . i give it 4 out of 10 for a few nice line and the fact that some of the girl actually look kind of nice .
