Growling vocals WAY too much. As a band they aren't even that heavy
most of the time (plenty of riffs would suit power metal) so they don't
need that grumbly cookie monster bullshit. Really wanky solo-fest, no
structure whatsoever. Sounds like they made a demo tape with about a
million different ideas and stuck it all together randomly. Not
impressive.
You forgot to mention that all those ideas are shit. And that the clean
vocals are annoyingly smooth and emotionless. And that when they do
bits in other genres, they don't even have any good riffs or melodies,
they just seem to be thinking "let's sound stereotypically like
country" instead of "I've written a cool riff in a country style". Like
the musical equivalent of an English speaker spouting random
foreign-sounding syllables and then being called bilingual.
