Recent Hong Kong action cinema has not exactly been known for its hero cops. Most often, one brave and valiant officer stands up for justice when all around him are corrupt or acting in self interest rather than for the good of the people. Shock Wave (拆彈專家) sees Herman Yau reteam with veteran actor Andy Lau turning in another fine action performance at 55 years of age as a dedicated, highly skilled and righteous bomb disposal officer who becomes the target of a mad bomber after blowing his cover in an undercover operation. These are universally good cops fighting an insane terrorist whose intense desire for revenge and familial reunion is primed to reduce Hong Kong’s central infrastructure to a smoking mess.
Some years prior to the main action, J S Cheung (Andy Lau) is undercover with a gang bomb loving bank robbers. When they decide to load up a few taxis with explosives, Cheung just can’t let innocent people and fellow officers get caught in the crossfire and so he blows his cover and tips the cops off to the weaponised motor vehicles. Head honcho of the gang, Blast (Jiang Wu), is not best pleased especially as his younger brother Biao (Wang Ziyi) gets himself arrested. Flash forward to the present day and Blast has come up with his plot for revenge – placing large amounts of explosives in the Cross Harbour Tunnel and taking everyone in the general area hostage until the authorities agree to release his brother and he’s satisfied himself in outwitting Cheung.
In this at least Shock Wave fits neatly into the mad bomber genre as Blast goes to great lengths to terrorise the public for irrational and entirely selfish reasons. Blast’s original twin motives centre on a need to get his brother out of prison and the need to destroy Cheung but Biao has decided one of the reasons he quite liked being in prison was that Blast wasn’t there and Cheung isn’t really interested in playing Blast’s game. Blast, as his brother points out, is someone who rarely considers the thoughts or emotions of other people, acting selfishly and assuming his own desires are the only ones which matter. This essential selfishness is echoed in a fairly subtle point about the financial impact of the tunnel crisis and how others stand to profit from it while hundreds people remain terrified and captive inside a giant tube surrounded by water which may soon collapse if Blast loses his temper.
Th mad bomber may be a cinematic staple but Shock Wave relies too heavily on familiar genre elements to make much on an impact of its own. Characterisation is often shallow in the hero cop vs insane criminal set up with supporting characters reduced to a single prominent emotion. The inevitable romantic subplot gives Cheung an emotionally fragile, recently divorced school teacher as an angelic girlfriend only to have her experience sudden qualms about getting involved with someone who does such a dangerous job.
Even if the narrative fails to impress, Yau produces an exciting visual spectacle reportedly spending vast sums of money building an exact replica of the Cross Harbour Tunnel. Filled with explosions, gunfights, and high octane action Yau keeps the tension high by turning the dial right down as Cheung and his gang do their thing with cool, calm military precision disarming everything from C4 to unexploded World War II bombs. At two hours, Shock Wave is pushing the ideal for an action thriller but largely makes its lengthy running time count despite a number of underdeveloped subplots.
A vehicle for Lau who also takes a producer credit, Shock Wave is defined by his performance as the dashing and heroic member of the bomb disposal squad. Jiang Wu’s mad bomber provides hearty support but is never given much to do other than emphasise his villainy with sneering taunts and occasional acts of cruelty. Cheung’s schoolteacher girlfriend Carmen, played by Song Li, is about as generic as they come seeming only to exist for the classic girlfriend in peril plot device but Song and Lau have good chemistry and the relationship does at least help to up the otherwise absent emotional content. Simply put, Shock Wave is an excuse for the ageing Lau to play the action hero once again and he plays it to the hilt. At times frustratingly formulaic, Shock Wave does manage to maintain the tension until the grippingly explosive finale whilst also paying tribute to those who run towards the crisis rather than away from it in full knowledge of the price they may pay in coming to the defence of ordinary people.
