“Spaceman” (** out of four) was a mostly lifeless outer-space melodrama in which an astronaut (Adam Sandler) is a half-a-year into his space expedition when he starts having concerns about his long-term survival and harks back to flashbacks involving his wife (Carey Mulligan) and is gradually helped by an ancient creature (voiced by Paul Dano) he discovers in the bowels of the ship. Nicely understated performance from Sandler and some effective moments in final third aren’t enough to sustain film, as it is too lethargic and laconic. Eerie music score by Max Richter is a definite plus.
