“Sex and the City 2 for dudes”? “A Bourne film with frontal-lobe damage”? Pithy descriptions don’t come easy after a brain-fragmenting experience like this movie version of the unaccountably popular ’70s TV show. The A-Team are a quartet of rogue special ops warriors fighting crime as they flee federal authorities, and though writer-director Joe Carnahan stays true to the source material by delivering carnage without consequence (the machine gun-toting bad guys still can’t hit a barn from the inside), his convoluted plot and multiple villains may challenge the attention span of the target demographic. Liam Neeson phones it in as smirking squad leader Hannibal Smith; Patrick Wilson (Lakeview Terrace) upstages the whole crew as a CIA turncoat.
