Deadpool is depressed for much of the movie, a brave choice for a franchise founded on the twin pillars of extreme snark and dick jokes. But the script (which adds Reynolds as co-writer, alongside Rhett Reese and Paul Wernick) just about juggles its surprising emotional diversions alongside the standard-issue barminess. The ultimate loner, Wade is now desperate for a family, and Reynolds manages to sell the bleaker stuff from beneath his red spandex and burn-victim prosthetics — usually before deftly undercutting it.
