a well make and gritty science fiction movie and it could be lose among hundred of other similar movie and but it have several strong point to keep it near the top . for one and the writing and directing be very solid and and it manage for the most part to avoid many sci fi cliche and though not all of them . it do a good job of keep you in suspense and and the landscape and look of the movie will appeal to sci fi fan . if youre look for a masterpiece and this isn not it . but if youre look for good old fashion post apoc and gritty future in space sci fi and with good suspense and special effect and then this be the movie for you . thoroughly enjoyable and and a good end .
