Rolling Stone also positively reviewed the album, describing it as "feel-good pop". Doug Brod in
Entertainment Weekly found "Glistening zero-gravity synth-funk that's mostly unembarrassing and at times shockingly vital", while reviews in
NME and
The Guardian were largely negative. Dorian Lynskey in the latter publication finding "Duran Duran are adrift in an unforgiving sea of disco-dad dance-pop, anaemic vocals and lyrics too distressingly awful to repeat in a family newspaper." Matt Dentler of
The Austin Chronicle called the album an "overproduced synth shuffle", going on to say "With too many songs trying too hard, Duranies will still go hungry for quality." In a review for
AllMusic, Andy Kellman wrote: "Even with a handful of forgettable songs beyond that, the album is easily the best one credited to the Duran Duran name since 1993's
Wedding Album." ==Commercial performance==
