i try not to be too negative when i comment on film so i shall start with the good point . this film do some thing well and particularly the jump shock and set up the atmosphere with the black brother and the lonely twin and but the dialogue be pretty rank and unbelievable ( no teenager in the history of the world have ever talk like that ) and the end twist be pull out of a hat and in an illogical way and that the film have at no point build up to . the acting be variable and with the background character do well and which be to be expect and give who be play them and and the teenage character vary from well do ( jake ) to not so good ( lisa ) . the directing be and again and variable and a i say previously and the jump shock be very well do and but the director seem a little too fond of the shaky cam effect at other point . while i understand the reasoning to this and with the exception of the drown scene and i do not think it add much to the film .
