The fast pace and action will keep you entertained and excited throughout the movie but try not to pay any attention to the story. As the hidden agenda of the mysterious voice is revealed it begins to take a series of lame turns. In the end you find yourself in a plot that makes you feel like Die Hard, War Games and Get Smart got thrown in a blender, pumped with added energy, and this was the result. If you pay careful attention you will become aware of a number of events that are written in to prevent exposition but don't seem practical (i.e. Nobody puts their bank card in an atm, selects withdraw and then begs the machine to 'come on' like they hope to get lucky at the slots. If you want to know if there is money in your account...check the balance.) Annoying moments like this are added just to emphasize a plot point. In this case, he has no money. A big waste since the following scene is his landlord trying to collect payment.
