Horrible... J Lo just has a big ego, as she produced, you keep seeing only her, it is one man show (or woman I should say ?) the script is sooo weak, boring. Also they stole some of parts from Terminator 2, like, I am ordering you not to shut down I am ordering you not to shut down :)
Robots are sooooo smart, that they plan everything but in the film they leave Jennifer so long that she can somehow wake up the robot, they do not see it, they are not aware of it... utter nonsense...
I watched it for free, in my netflix, so dont even think of paying money for this. Waste of time, money.
