 Carl Wilson of "Billboard" rated it 3.5 out of 5 stars.His review stated that "The album is a good-faith effort to match or even outstrip the band's onstage eclecticism, and the musical personality shifts help relieve the group's tendency to blandness, providing cover for Brown's dutifully generic, if personable voice.Some longer-standing fans, though, might judge the changes as diabolical as the two-faced Robert Louis Stevenson character that lends the album its name."
