The affectionate documentary "It Ain't Over" has a split personality. Longtime baseball fans can revel in black-and-white archival footage showing Hall of Fame catcher Yogi Berra in his prime at bat and behind the plate in that era's baggy flannel uniforms.

The universe of non-fans can savor Berra as a pop-culture legend, thanks mainly to his trove of purported Yogi-isms. Those much-quoted twists and turns spark chuckles while also shining at least a glint of wisdom.
