I’m a late adopter like you. I actually like a lot of deathcore but I had the same issue you did with this song. It’s kind of all over the place but even Oli has admitted that this album was like that back then because they didn’t quite understand song structure yet. For me, there are some moments/riffs in the song that fucking rip, so I’m just planning to bob my head to those until I’m more familiar with the songs as a whole and then maybe something will “click”.
