Speaking about the album, lead vocalist Tyler Smith has stated:

Dark Matter is the result of our most in-depth writing and recording sessions we've done, and is something we consider to be our most dynamic and expansive album to date. This record completely defines and expresses who we are, and where we are going, taking the listener to the darkest and most honest places our band has dared to venture.^{[citation needed]}

The album received mostly positive reviews from critics. Already Heard rated the album 4 out of 5 and: "In reality though, Dark Matter marks a bold new chapter for The Word Alive, one where their 'pretender' tag is ditched in favour of something much more representative of this newfound greatness. Because for an album that sheds any much-maligned genre tropes in favour of a genuinely exciting, melodic sound, there can't have been many who'd have thought it'd be The Word Alive to pull it off."^[5] Kriston McConnell from New Noise rated the album positively calling it: "Dark Matter is the most mature record the band has released to date. Instead of focusing on breakdowns or screams the songs are more about the lyrical content. This is a direction the band has been heading in for some time, and this album is a culmination of that effort. It's slightly disappointing that the group has opted to deviate from the sound they created in Deceiver and Life Cycles, but Telle has been in the music industry since he was a teenager so a shift in sound is to be expected. If there are fans who were hoping they'd go back to their older sound, then they will be disappointed. The album is more similar to Real., and they will likely continue on that path for the rest of their career as a band."^[6] New Transcendence stated that "It's a difficult task to improve on a previous album, let alone do it three times in a row. But The Word Alive has managed to put out the best record of their career with the best metalcore album of 2016 so far. A triumph that'll be very hard to beat, the prowess on every song can't be overstated. So do yourself a favor and pick up this glorious album now."^[7]
