Other movies have told stories based around young men who lash out at society, but Ramsay blends the reality of that sort of situation with the type of bad kid horror subgenre seen in films such as "The Bad Seed," "The Omen" or "Orphan," only basing it in reality rather than doing it as a sensationalist genre film.
It's found in such brilliant short fictions as Henry James's The Turn of the Screw (filmed as The Innocents), Paul Bowles's Pages From Cold Point and, more recently, Doris Lessing's The Fifth Child, as well as horror movies such as The Bad Seed and The Omen and in real life in the James Bulger case.
Kevin is a horror movie trope -- ripped from movies like The Bad Seed, Village of the Damned, The Omen, and the recent Orphan -- far too menacing to be even remotely connected with anything real.
Motiveless malignancy in cinema youngsters is no rarity though, except for blood-will-out The Bad Seed, ordinarily from demonic possession.
From "The Bad Seed" to "The Omen" to "The Good Son," kids have been creeping us out for years.
As a result, "We Need to Talk About Kevin" comes across less like the powerful and profound drama that it clearly wants to be and more like an excruciatingly arty version of the old horror-exploitation standby of the killer kid, a trope that has been deployed in the past in works ranging from the Broadway-sanctified "The Bad Seed" to grindhouse insanity like "The Children" to mass-market takes like the Vera Farmiga vehicles "Joshua" and "Orphan."
