This review may contain spoilers. I can handle the truth.
Okay, so the ending got a little sappy and I thought it was very lazy writing to have hackers get access to every surveillance-camera in the world - especially when characters make their secret appointment UNDERNEATH one of those cameras. Having said that, I thought the major part of the film was really well written and executed. Also, it didn't treat its audience as fools, which, in this genre, is nice for a change.
