Stephen Thomas Erlewine's review: "Not all of the experiments work, but Def Leppard sounds revitalized, particularly when they attack a straightforward rocker."

"All in all, the most exceptional makeover of the year." 3 1/2 stars.

Jon Wiederhorn's review: "Slang rarely rocks; Def Leppard seem too consumed with sounding hip to let loose any real dynamic guitar squalor."
