This could have been a good EP. Leave off the boring "These Walls," the cringe-worthy "Never Enough," the decent, but ultimately forgettable "The Answer Lies Within," and the overdone, but nothing special "Sacrificed Sons," and you have a good EP of:
"The Root of All Evil"
"I Walk Beside You"
"Panic Attack"
"Octavarium"
Actually, if this were the 70s, that could have been a good full-length studio record. I know some will say, "Yeah, but leaving off anything ruins the full circle aspect of the title song and blah, blah, blah," but who cares?
