This was clearly a formidable undertaking filled with sweeping imagery, motion-capture performances and tons of visual effects, all being projected in overwhelming IMAX 3-D. So it’s hard to figure out what happened with Jones and “Warcraft.” It’s as if the endeavor swallowed him whole. (Plus: If one Sam Rockwell is good, two Sam Rockwells are great.) Jones’ 2011 follow-up, the time-travel puzzle “ Source Code,” felt like a bit of a let-down by comparison but it was thrilling and challenging, and it showed his evolution as a filmmaker with a bigger cast and more expensive toys. His debut, “ Moon,” was my favorite movie of 2009 it was about mind-blowing, existential stuff but it had real verve, immediacy and heart. With just two features to his credit, Jones has shown a real knack for taking complex, sci-fi stories and telling them in clever, intimate ways. And it brings me no joy to report that to you because “Warcraft” comes from a filmmaker whose work I’ve been a big fan of: Duncan Jones.
