“Polar” (*** out of four) was a wildly entertaining Netflix action thriller about a world-weary former top assassin (Mads Mikkelsen) who begins to settle into retirement when his former employer (Matt Lucas) double-crosses him and decides not to pay him his pension and he finds himself in a final fight to the death for his life against a band of ruthless younger killers. In-your-face mix of style, ultraviolence, and sex never stops moving and thus never stops entertaining. Goes too far at times but excess is the name of the game here. Mikkelsen is perfectly cast in the lead and Richard Dreyfuss has an amusing cameo as a turncoat former friend.
