Team Boo garnered positive reviews from music critics. Tim Sendra of AllMusic praised the album's upbeat production and the vocal work of Gardner and Hammel giving life and exuberance to even slower tracks like "Parachutes (Funeral Song)" and "An Experiment", saying that "Team Boo is a record that will make even the staunchest nonbelievers believe in the power of simply played, honest, and energetic pop music again."[1]Pitchfork writer Rob Mitchum said that despite some slow-placed tracks, the album was a return to form into My Solo Project territory thanks to the production work of John Croslin and Jim Eno leading them there, saying that "Team Boo turns out to be a surprisingly respectable junior-year effort-- one that puts Mates of State in the small minority of indie-pop bands that don't fall under the one-album-and-out rule."[2] Mackenzie Wilson of Rolling Stone praised the duo's elegant and idiosyncratic musicianship complementing their vocal harmonies, saying that "Gardner's girlish vocals snugly wrap around her husband's boyish charm, letting on to Mates of State's genuine love for music as well as for one another."[3]
