I'm a big fan of the hit TV series '24', which calls for a lot of suspension of disbelief, but nowhere more so than the systems they've got running up at CTU. Not only is their system tight, but everyone else's in the world that they connect to is tight too.
Old Chloe can hack into anything in about 18 seconds. Pull up a schematic of this, show me the layout of that, get past this firewall, uplink from this cellphone... but to make it just a little more real, couldn't they have her sit for several minutes seeing an hourglass once in a while? A blue screen of death, host not found, server not available, 404 page not found, an error has been found running scripts on this page, etc.. etc...?
