Remember what the world was like when anyone last cared about an M. Night Shyamalan movie? George W. Bush was in the White House, Vanessa Carlton was on the radio, and you couldn’t even tweet about how cool you thought “Signs” was because Twitter wasn’t even around yet. The early 2000s seem like several lifetimes ago, especially for the director who soared early in his career with “The Sixth Sense,” “Unbreakable,” and, yes, “Signs,” and then spiraled into creative freefall through the likes of “The Last Airbender” and “After Earth.”
