George Clooney inspires as a director. Here, more than ever. “Confessions of a Dangerous Mind,” “Up in the Air,” and “The Tender Bar” are a few of his films. Clooney’s in them, too, because he knows a good story when he sees one and obviously where he best fits. Now, he offers “The Boys in the Boat.” Will it be up for Best Picture? No. But is it worth watching? Without a doubt.
