Gavin Haynes from NME has said that the song is "mainly frazzled, sonically-saturated electro that reminds us of Speakerboxxx/The Love Below at its most boxing-clever".

[6] Robert Copsey from Digital Spy rated it with 4/5 stars, saying "This latest single has a head-spinning structure that sets it apart from the average club track, while the singer uses the accompanying video as an excuse to rock a Native American headdress.

[7] A negative review came from Fraser McAlpine from BBC Chart Blog who rated it 2/5 stars, saying "There are dance noises, there is singing, there are words, but they don't ever synthesise into something that makes any kind of impact whatsoever".

[8] The Unreality Shout review was positive, awarding it 4/5 stars, saying "'4th Of July (Fireworks)', is a wonderfully written love song.

It recalls the same kind of production that was the norm for dance tracks back in 2000–04, whilst enlisting the help of DJ Ammo to update things to create a songs that is both stuttering and slurring, both cold and warm, both happy and melancholy, with a pulsing bass-line, and Kelis' brassy vocals showering the track with icy classiness".

As the video ends it shows Kelis waving her arms in the air with effects of fire burning.
