Fireworks Magazine described Quietus of Autumn thusly:
"A cross between Nightwish and Children of Bodom, Mute Prophet’s third album is one of the most unique symphonic metal experiences in a long while! Seductive singing and sinister screams. Heavy riffs, shredding solos and epic orchestrations. Quietus of Autumn combines the symphonic power metal base with prog, melodeath, djent, and so much more!
The album is simultaneously a love note to symphonic metal’s 30-year history, and a defiant refusal to stay bound within its typical framework. The songs pivot between warm nostalgia and irreverent iconoclasm, Mute Prophet’s respect for their roots competing with their drive to take symphonic metal to places never seen before."
