Damien Chazelle, Hollywood’s celebrated enfant terrible who burst onto the scene like a supernova with Whiplash and La La Land, delivers exactly the opposite of his expected output with a brooding and torturously technical biopic about Neil Armstrong, and it’s no wonder the sky-high critical and box office promises of First Man (C-) have remained unusually earthbound. Ryan Gosling’s interior performance as an Armstrong who is near-paralyzed by human interaction after suffering personal tragedy may be imbued with a north star of accuracy, but it’s just not what people go to inspiring movies about heroes to see, and all the sullen solemnity eclipses any attempts at showcasing the highs and lows of the early space program. Claire Foy’s similarly macabre take on his long-suffering spouse doesn’t help either in penetrating the pioneering spirit behind this dark side of the moon. The film lingers on highly technical elements of several space missions so long that by the time the Eagle lands, the viewer is just appreciative to get on with it. Perhaps the most annoying element of the film is its score by Chazelle’s jazzy frequent collaborator Justin Hurwitz, whose music sounds lost between a ghoulish fun-house and an Italian café for much of the film’s prodigious duration. A few supporting cast members such as Corey Stoll get some nice bits, but it doesn’t look fun sharing orbit with a sad sack protagonist. The film isn’t clear what it’s trying to say or even if Armstrong enjoyed his day in the sun on the moon. Adrift in storytelling and pacing, this linear lunar biopic shines brightly for just a few moments but remains largely a waning gibbous.
