Live Free or Die Hard is like somebody took poor John McClane (Bruce Willis) and dropped him into a typically ludicrous techno-terrorist plot, forcing him to babysit Movie Hipster Computer Geek #72 (Justin Long) while hunting down the bad guys.
Thin plot has to do with an angry supergeek (Timothy Olyphant) wreaking computer havoc on the United States. He gets more than he bargains for when he sends his goons to kill unwitting helper/potential witness hacker Matt (Long), who luckily meets McClane first. Action ensues as McClane and Matt track down the bad guy, dispatching his evil henchmen one by one.
When McClane is killing dudes the old fashioned way, the movie is decent Die Hardesque fun. But when he is stunt-driving trucks and cars, and preposterously facing down Harrier jets, you might start to wonder why they even bothered with Bruce Willis when they could have got Jason Statham for less.
But Willis is great, pure McClane. Maggie Q is awesome as Evil Asian Computer Expert/Kung Fu Master, and Justin Long makes the most of what little he is given.
Suspend disbelief, lower any Die Hard expectations, and you might manage to enjoy it as popcorn action fluff.
As an action movie, I give it a 7.
As a Die Hard movie, I give it a 4.
