ReviewEntertainment Weekly (B+): Poetry it's not. Still, there is something delightfully escapist about Blackout, a perfectly serviceable dance album abundant in the kind of bouncy electro elements that buttressed her hottest hits (''I'm a Slave 4 U,'' ''Toxic''). Say what you will about Spears' personal life, but there's no denying that the girl knows how to have a good time.
The Guardian (4/5 stars): Blackout unleashes a torrent of ferociously distorted synthesizers, electronically treated vocals, snapping drum samples and bovver-booted glam rock beats. The results are largely fantastic. ... It's a bold, exciting album: the question is whether anyone will be able to hear its contents over the deafening roar of tittle-tattle.
All Music Guide (3.5/5 stars): Blackout is state-of-the-art dance-pop, a testament to skills of the producers and perhaps even Britney being somehow cognizant enough to realize she should hire the best, even if she's not at her best.
