“Free Solo” scared the crap out of me. I can’t think of any other movie that frightened me more than this one, which won an Oscar a week ago and airs — commercial-free — on the National Geographic Channel on Sunday at 7 p.m.
I’m a complete coward when it comes to horror films, though I can at least tell myself that horror films aren’t real. “Free Solo,” on the other hand, was all too real to someone like me, who is terrified of heights. It chronicles Alex Honnald’s June 3, 2017, ascent of El Capitan, the sheer rock formation at Yosemite National Park in California.
