A real blast for the die-hard fans Bruce Willis and Jai Courtney do battle as father and son in A Good Day to Die Hard. SOME parents are impossible to please. On discovering that his son Jack (Jai Courtney) is a CIA agent working undercover in Moscow, rather than being proud, John McClane (Bruce Willis) is scornful. Having followed Jack to Russia, John spends the first half of the movie sneering and complaining. This character used to be a fun guy. Now he's a pain in the neck. Willis's grumpy performance isn't the only thing amiss in the fifth film of the series. Director John Moore (Max Payne) can't direct a simple car chase coherently. His camera shakes and zooms in and out for no reason. The screenplay by Skip Woods (The A-Team) is equally bamboozling - something to do with the feud between a political prisoner, Komarov (Sebastian Koch), and a corrupt politician, Chagarin (Sergei Kolesnikov). Intrigue is not a strength of the Die Hard series. Born during the Reagan era, the films usually avoid murky politics in favour of straightforward Bruce v the bad guys. Blame The Bourne Identity, the action movie that changed action movies, for leaching the fun out of this one. A wobbly camera and a confusing plot don't make a movie sophisticated any more than a grumbling hero suffering a mid-life crisis makes for charming company. The convolutions of the story don't hide the fact that it is also very silly. The two McClanes eventually end up in Chernobyl in pursuit of a bad guy called Alik (Radivoje Bukvic) and, while the villains are careful to don protective gear, Jack and John waltz in cloaked in nothing but swagger. What do these guys care about a little radiation? They can jump through windows and fall through roofs without any ill effects. Yippee-kai-yay. Australia's Courtney is a perfectly able action man: under different circumstances he and Willis would make a good team. As it is, the shortest of the Die Hards is by far the most tedious. Even die-hard fans will be disappointed. Now showing; rated M; running time 98 minutes.
