"In short, this isn't the greatest album Within the Ruins have ever written and nor is it their worst. It contains material that meets the heights of hallmark records like 2014s Phenomena and its predecessor Elite, and at times even surpasses them, but Black Heart's incongruous midway point leaves a general tang of inconsistency in an otherwise satisfying smorgasbord of malicious riffing and tasty hooks. The headlines are that for what the band gets right, they do incredibly well".
