[5] Leave Me Alone has been described as a set of cheerful, casual, lo-fi, guitar-driven pop songs, with many critics referring to the music as "surf-rock".

[6] Leave Me Alone received mostly positive reviews upon its release, largely describing the album as playful, energetic, and exuberant, although some critics identified a more serious and gloomy side to the music.

Noel Gardner of NME commented on "the impression [the album] gives of Hinds as a tight-knit girl gang,"[12] and Spin's Harley Brown wrote that the band often sounds like "they got carried away with the sheer good fortune of discovering their musical talent -- and how much fun it is playing with each other.

"[6] The dual vocalists were identified as one of the best aspects of the album, with Quinn Moreland of Pitchfork writing that "the best moments on Leave Me Alone occur when Cosials and Perrote are going all-out, belting together without restraint.

"[4] The album has also been negatively criticized for not expanding creatively beyond other bands in the genre, with Spin's Gardner writing that "it's a little hard to avoid feeling like you've heard this one before."
