De internasjonale filmmagasinene Screen, Hollywood Reporter og Variety roser En ganske snill mann.
«Norwegian director Hans Petter Moland and Swedish actor Stellan Skarsgard are a match made in cinema heaven. They have worked together before, on Zero Kelvin (1995) and Aberdeen (2000), and presumably have a shorthand. In the criminal comedy A Somewhat Gentle Man they achieve a cool, deceptively simple minimalism which is both perfectly timed and brilliantly pared-down. (…) Hans Petter Moland’s style never impedes on the humanity of his characters and his affection for them is never in doubt.» Les resten av anmeldelsen.
«Played for laughs drawn from characters rather than funny lines, the Norwegian film is a charmer with Stellan Skarsgard for once in a role worthy of his attention. Although a little long for its own good and with a score that’s too bouncy by half, it’s the kind of film that sneaks up on you and leaves a warm smile. It should do very well in international markets and festivals will line up to offer applause.» Les resten av anmeldelsen.
«With its off-the-wall-and-well-out-the-door humor, flashes of violence and broad-brushed, quirky personalities, the pic feels almost like an homage to older Coen brothers movies (they might as well retitle it «A Somewhat Serious Man» and be done with it). At the same time, the characters’ distinctive genial gruffness and adherence to bourgeois propriety even in the shabbiest circumstances, and the underplayed comedy throughout, mark the pic’s sensibility as distinctly Scandinavian.» Les resten av anmeldelsen.
