Magma was met with favorable reviews from music critics. At
Metacritic, the album has received a score of 79 out of 100 based on 12 reviews, indicating "generally favorable reviews". In Dom Lawson's review for
The Guardian, he gave the album 5/5, writing that "
Magma is the kind of album that metalheads would love non-believers to check out, if only because it confounds all the usual stereotypes about the genre being unimaginative and dumb." Adrien Begrand's review for
Spin likewise received the album positively, writing that on
Magma, Gojira "strip their distinctive sound down even further, most often building songs around one insidiously catchy riff and resisting self-indulgent flights of fancy. It's common for young acts in modern metal to show astonishing technical skill but no sense of restraint. By contrast, there's little else out there like the taut, minimalist
Magma right now."
Rolling Stones Daniel Epstein noted that
Magma marks a stylistic departure for Gojira compared to previous albums. "Largely absent are the epic song arrangements and neck-snapping displays of instrumental wizardry that marked their recordings up through 2012's ''
L'Enfant Sauvage''. Instead, new tracks like 'The Shooting Star', 'Stranded' and 'Pray' are more about finding a fearsome groove or riff and squeezing it for every last drop of darkness and catharsis." He noted the death of Joe and Mario Duplantier's mother as a likely influence on this development. Epstein also compared the album to
Metallica's 1991
self-titled album and
Mastodon's 2011
The Hunter, writing that "for those who can appreciate a tightly focused hard rock album infused with emotions that are often just as heavy as its riffs,
Magma offers a listening experience that is as rewarding as it is therapeutic." Writing for
Pitchfork, Zoe Camp described
Magma as "their most accessible release yet, melodically immediate and charged with emotion." Camp sided with Epstein and other critics in considering the album a stylistic departure from previous releases. Camp wrote that on
Magma, Gojira "deliver a taut, catchy crossover effort that inoculates their [heavy] metal with equal parts melodic immediacy and emotional intimacy, while retaining the pillars of their caustic panoply: mathy riffs, uncommon time signatures, ferocious, death-metal-styled vocals, and above all, overpowering anxiety. The new sound's largely a consequence of the Duplantiers' grief; their mother died during the album's gestation, forcing the brothers to get out of their own heads and revisit the material they had so far—often fighting back tears during the sessions." Joseph Achoury Klejman of Paris'
Rock & Folk praised the musical direction and gave the album 4 out of 5; he wrote, "Gojira even breaks its own codes, offering shorter pieces than before, thus gaining in efficiency without losing power". He concluded his review by describing "Liberation" as "an acoustic and instrumental piece where
ethnic percussions are invited to finish in style a masterful album". Author Marie-Hélène Soenen felt that the album was "Imbued with a more atmospheric and mystical
aura than its predecessors". Music critic Naiko J. Franklin of Paris'
Hard Force magazine considered
Magma as Gojira's best work thus far and "that of maturity". He found it "Balanced, colourful, sometimes exotic, very often bewitching, dark and melancholic, powerful and refined, overflowing with rage and emotion, absolutely free of any filler or repetition". He concluded by calling the album "a definitively affirmed style, but above all defended with as much ferocity as grace". == Accolades and legacy ==
