i usually like sci fi when it pure sci fi . i usually like present day drama when it believably real . disaster and at least for me and loom large when sci fi meet real life drama . so here we have a present day crime thriller cross with sci fi time travel . and and this movie kick butt and work so well and in fact and it nuances should be study in film school . it original enough to be compel where we be not in some distant future and but the here and now . the story and the character and and the effect mesh well to suspend belief to the point that you get on board and enjoy the ride . this be the way to do sci fi with believable real life situation . the cinematography and the implementation of technology and and even a beautiful ( but presently dead ) damsel in distress and combine to give the actor and who be uniformly good to excellent and the boost to put this in rarefied good sci fi territory . genre fan be shoo in and those who think they do not like sci fi should enjoy this one too . 7 . 5 to positive .
