Ned Raggett in his review for AllMusic wrote, "The bombastic 'Innocence and Wrath' starts To Mega Therion off on just the appropriate note – Wagnerian horn lines, booming drums, and a slow crunch toward apocalypse. ... With that setting the tone, it's into the maddeningly wild and woolly Celtic Frost universe full bore, Warrior roaring out his vocals with glee and a wicked smile while never resorting to self-parodic castrato wails. 'The Usurper' alone is worth the price of admission, an awesome display of Warrior's knack around brute power and unexpectedly memorable riffs." According to Raggett, "other prime cuts" include "Circle of the Tyrants", "Dawn of Megiddo", "Tears in a Prophet's Dream", "Eternal Summer" and "Necromantical Screams". Raggett concludes his review by stating that the album "is and remains death metal at its finest".^[2] Canadian journalist Martin Popoff considers the album "a black metal landmark" and "the most consistent example of early death metal that exist". He remarks how "the band had decided to delve more unto the extreme" and praised Tom Warrior's "surprisingly accomplished" lyrics and the mix of death, black and doom metal with a pinch of ambient music.^[3]
