Also: IMAX previews are played way, way, way too loud.
Ahem. Now that I've gotten my old person reactions to modern movie-going out of the way, Free Solo was great. The movie chronicles rock climber Alex Honnold's quest to be the first (and quite possibly only) person to free-solo El Capitan - 3,000 feet, without a rope - in Yosemite National Park, which is about the most insane thing a climber has ever done. The filmmakers are also friends with Alex, so the fourth wall gets broken as they fear for his life in the midst of filming him. This makes for a very personal film and even though SPOILER he doesn't fall off the face of the cliff and die, it's intense.
