“The Shamrock Spitfire” (** out of four) was a frustratingly generic WWII true story of Brendan “Paddy” Finucane who at age 21 became the youngest ever wing commander in the Royal Air Force and became a celebrated war pilot. Not bad, with some good acting and camaraderie amongst the actors and squadrons, but too limited in scope and scale to make much of a mark or desired effectiveness. History buffs and war-film completists might want to add half a star.
