“Operation Finale” (**1/2 out of four) was an adequate melodrama based on the true story of a group of Israeli secret agents (Oscar Isaacs, Melanie Laurent, Michael Aronov, and others) who set out to find and capture escaped Nazi officer Adolf Eichmann (Ben Kingsley), who many believe was the real mastermind and organizer of The Holocaust, and they brought him to trial where he was sentenced to death. Inherently gripping story plays out too leisurely and is never as powerful or compelling as it should have been although good performances help it remain watchable. Film historians will note the ironic casting of Kingsley as the Nazi officer especially after playing a pivotal and crucial role in “Schindler’s List.”
