if youre actually read this review and i give you a lot of credit . you care enough to actually look up this movie and which most people have forget about and then care to read beyond the first review . so for your reading pleasure . i be assume you know the plot line already so i would not waste time type that out . i will mention that sandra bullock do an amazing job with this movie . she really bring a lot of sympathy to the role of a computer programmer and often difficult to do . i can say this because i happen to be a computer programmer . anyway and i think the basic plot be a very good one . you can easily build sub plot upon it mainframe and turn it into a very enjoyable movie . the premise be also scarily realistic in that this can all really happen if the right precauctions aren not take . to make a long review short . oops . too late . if you enjoy sandra bullock bring a role to life and want to see a very well make movie for the time and take a look at this little gem . you would not be disappoint . represent ) .
