The reviews are mixed for Adele's new album, "25," as critics and fans couldn't quite agree whether it's her best album or worst.

Neil McKormick of The Telegraph said that Adele made a worthy follow-up to the critical and commercial success that was the "21."

"A lot is said about Adele's fantastic singing but the key to her global success is surely that she gives herself material worth wrapping her chops around," he wrote. "25 is crammed top to bottom with perfectly formed songs - elegantly flowing melodies, direct and truthful lyrics and richly textured production - all sung as if her life depends on it."

Jon Caramanica of The New York Times said that Adele stayed true to herself and that's not a bad thing.

"Her music is like time-lapse photography of a busy street: Small parts move, but the structure of the whole picture remains essentially intact," he said. "What sets her apart, though, are those steady parts: a gargantuan and smooth voice, deployed with casual control and a cathartic fluency with heartbreak."

But Greg Kot of the Chicago Tribune said that Adele's new album is stuck in a time warp.

"This is not to diminish Adele's skills, her poise and precision as a multi-octave vocalist, her sincerity in addressing her personal struggles," he wrote. "But there's a sense of 'we've been here before' on '25' that makes it seem as though Adele, the artist, has taken a back seat to Adele, the meal ticket who would single-handedly save the music industry."

The Guardian has a similar assessment about Adele trying to wring the same issues covering "21" for her new album, "25."

"It's an album that could have done with more stuff like that: more variety, more sense of an artist using the space and freedom that shifting 30m units buys you to move on, at least a little," Alexis Petridis wrote. "As it is, 25's big issue is that, in every sense, it dwells a little too heavily on the past."

NME, meanwhile, deemed Adele's new album, "25" as "too safe."
