These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Broken Base: Did the band peak with The Red in the Sky is Ours and devolve into a sound that served as a bastardization of everything that extreme metal stands for, or did the band consistently improve until they released the fullest distillation of their sound with Slaughter of the Soul? Ask a fan and the answer will be given to you vehemently and passionately.
Fandom Rivalry - With Dark Tranquillity and, to a lesser degree, In Flames, depending on who you ask. Unfounded, as all three bands have toured together, are all currently signed to the same label - Century Media Records, and helped each other from time to time.
Seinfeld Is Unfunny - So many damn bands have copied the chug-heavy power riffing style present in Slaughter of the Soul, it can be hard for first-time listeners to figure out what was so special about it.
Signature Song - "Blinded by Fear", the opening track of Slaughter of the Soul.
They Changed It, Now It Sucks - As with the popularity reaction above, many fans really hated Slaughter of the Soul; they're generally easier on Terminal Spirit Disease, despite the fact that it was with TSD that At the Gates turned to melodeath.
For many, the biggest complaint about Slaughter of the Soul has to do with the fact that the songs and riffs have less variety than any of the previous albums moreso than the change to melodeath itself. There's also the fact that the riffs from Slaughterhave been recycled by so manyMetalcore bands, that some have even taken to retroactively labeling it as a Metalcore album. With Metalcore being The Scrappy of the metal world currently, the association automatically gives the album a fairly vocal Hate Dumb.
