'The Flash' races into the multiverse in a movie that clicks on all cylinders

Marvel's various forays into the multiverse have yielded a mixed bag creatively, so credit DC/Warner Bros. with striking gold on the first try with "The Flash," a movie that wears its love for the comics that inspired it on its crimson-streaked sleeve. Funny, action-packed and effectively touching, anyone familiar with the DC stable of heroes should run, not walk, to see it.
