Kick-Ass sets itself up as an unadulterated exposé of the teenaged mind. Tired of being mugged by high school thugs in a Manhattan that's notably scummier than the real thing, our hero Dave Lizewski (Aaron Johnson, a hot young thing given a perm-and-glasses nerdover) wonders, in a hilariously put-on and intermittent Brit's New Yawk accent, "How come nobaddy's eva tried to become a suppahero?"
In a New York that is part past, part near-future, and part Canadian soundstage (street crime and graffiti are at pre-Giuliani levels, but gadgetry and weaponry are cutting-edge), Dave soon learns the hard way that trying to intimidate thieves while wearing a ridiculous green wet suit/superhero getup elicits first laughter, then a beatdown. But as soon as he's back on his feet — this time with damaged nerve endings and steel bone reinforcements, thus minimizing his ability to feel pain — he's back on the streets, looking to fight more crime. His bumbling attempt to battle a four-man crew attracts a cell-phone-cam-wielding crowd — which in turn scares off the bad guys. "Who are you?!?" asks an amateur videographer. Ready for his close-up, Dave sneers, "I'm Kick-Ass!" With that phrase and Dave's heroic antics catapulted into the memespace, Kick-Ass is real.
Directed by Matthew Vaughn, Kick-Ass is an adaptation of Mark Millar and John Romita Jr.'s graphic novel. Vaughn approaches the teenaged brain as not necessarily a function of age — adults and prepubescent girls are here equally afflicted with an identifiably adolescent lack of impulse control and concern for consequence. As Dave's double life takes shape, we're introduced to Mindy Macready (Chloë Moretz), a pigtailed blond preteen whose daddy, Damon (Nicolas Cage), a wild-eyed ex-cop turned ex-con, trains her to take a bullet and twirl knives for the inevitable day when "some junkie asshole pulls a Glock." The happy family sees the viral Kick-Ass video on the local news, and a light bulb goes off: There's suddenly a socially acceptable context for their hyperviolent bonding exercises — and for Damon's jones for revenge against the Mafia don who set him up and sent him to prison. Soon, Damon/Big Daddy and Mindy/Hit Girl, who, unlike Kick-Ass, are actually good at ass-kicking, are wasting drug dealers behind the scenes while Kick-Ass gets all the media cred. Eventually, they'll have to join up to wage full-on, caped-crusader-on-gangster war.
In a rare twist for a long-in-the-works film that strives to be current, the characters' reliance on technology isn't contrived. In its first half, Kick-Ass offers a fairly astute if light assessment of how new media has given fresh outlets for the age-old instincts of both heroism and hero worship. In an accurate mirror of teen technocratic priorities, Dave seems to be in the crime-fighting game less to save lives and more for the MySpace glory, which leads to newfound confidence, which gets him laid — and at that point, he's ready to give up the hero racket for good. But no hero (and certainly no would-be franchise kickstarter) gets off that easy, and thus Kick-Ass launches into its second hour, a mess of random source cues and progressively brutal action set pieces shot through with shaky moralism (when a child murders grownups, Kick-Ass wants us to cheer, but when an adult man pummels a little girl, Kick-Ass wants us appalled). As narrative and thematic clarity fall by the wayside, Kick-Ass devolves into a show reel for its own ancillary characters; expect to see a lot of slutty Hit Girls toting mock bazookas this Halloween.
For all of its self-conscious edge, Kick-Ass feels as though Vaughn took all of his potentially powerful material and filtered it through distancing devices. It's a teen-angst movie filtered through the comic book form (literally, in the case of a number of framing techniques designed to situate Hit Girl and Big Daddy in the story) in which the characters themselves respond to reality only as filtered through comic books, TV, and social networking. Most offensively, it takes the strain of Asian pop culture centered on uniformed (and often panty-flashing) schoolgirls coolly and competently kicking the asses of grown men, which has already been filtered into American pop culture by Quentin Tarantino, and reduces it to shallow shock lines. Are we really supposed to get excited about a little girl saying words like cock and douche? Anything passed through this many filters would come out weak. Never as shocking as it thinks it is, as funny as it should be, or as engaged in cultural critique as it could be, Kick-Ass is half-assed.
