“The Theory of Everything” is biopic about one of the most brilliant people in the history of the planet, the renowned astrophysicist Stephen Hawking. He’s a man famous for thinking in boldly innovative ways, yet his story is told in the safest and most conventional method imaginable. Director James Marsh — an Oscar winner for the 2008 documentary “Man on Wire” — has made a strongly acted, handsomely crafted film that nonetheless feels bland and unsatisfying. My mixed RogerEbert.com review.
