In Irish crime drama "Barber" Aiden Gillen (likeable as ever as he channels Richard Gere) is a grizzled ex-police private dick who's hired by Diedre Donnelly to track down her missing granddaughter, which leads him into a relatively simple #metoo related case with classic elements like a dodgy politician, corrupt police (Liam Carney) & a powerful bullying stepfather (David Herlihy). Meanwhile Gillen has his own issues to deal with, as society (Dublin's in particular) changes around him. It's sluggish, tv-standard fare but Gillan and its interesting broad subject matter (from writers Fintan Connolly (who also directed) & Fiona Bergin) make it passable enough.
