Critical reception
At Metacritic, which assigns a normalized rating out of 100 to reviews from mainstream publications, Rocket received an average score of 82, based on 21 reviews, indicating "universal acclaim". Writing for Pitchfork, Ian Cohen said, "Sometimes, there really is no substitute for the revelations that come when an artist unlocks the mysteries of their work. But it's certainly the reason why Rocket feels like one of the year's most endlessly generous records, as Alex G's restraint is our gift that keeps on giving." AllMusic's Marcy Donelson stated that Giannascoli is "far from catering to the mainstream here, but through it all, the wistful chords and progressions that are such a trademark of his sound act as a sonic through-line. Also uniting the album are immediate, conversational vocals and, similarly, an impression that accompaniment is gathered in a circle playing along by ear." David Sackllah of Consequence of Sound said, "As inscrutable as it can be at times, Giannascoli never betrays his purpose, making Rocket his most developed and accomplished album yet." The A.V. Club critic Josh Terry said, "Even though Rocket sometimes feels messy, only a songwriter as prolific and uninhibited as Giannascoli can make the chaos this thrilling and affecting." Sam Shepherd of MusicOMH wrote, "Alex G's skill is in tackling difficult subjects and squeezing them into the most wonderful kernels of pop, and once again, he’s succeeded here." DIYs Will Richards said, "Slowing down and refining his output has allowed Alex the time to make Rocket a brilliantly considered next step. It's also his catchiest record yet." Sammy Maine of The Quietus wrote, "The raw and at times, ferocious navigation of the album soars in its earnest delivery and marks a career-defining release for Alex G." The Guardian writer Harriet Gibsone stated, "It is at times unpleasant, but Rocket has no ambitions to score a dinner party. The frantic interchanging of emotions--like the internal monologue of someone with a hellish hangover at ATP in 2009--is a challenging, ambitious progression."
