Many Autopsy fans consider their work after Severed Survival and Mental Funeral to be less good, and a deviation from the sound of the band. It is true that Autopsy changed with this record. They started combining (crust?) punk and hardcore influences into the songs, and made tracks of shorter lengths. Aside from that, however, the band does have their old sound. There is a doom-y feel to some songs and solos in the same style as Mental Funeral. The lyrics are ridiculous as usual, but have reduced in quality. It feels as if Reifert was trying to shock listeners more by writing in a less skilled manner about topics more disgusting than before. After track nine or ten, the album really started to drag for me and I couldn't wait for it to be over. Where Mental Funeral might have felt a little too long, Acts of the Unspeakable feels horribly like it overstays its welcome. I guess to conclude, this album still contains the old band's sound to a degree, but are more tiring and come off as more boring.
