you kinda expect some level of preachy crap with underoath, but these two albums were unbearable.
also, I've never seen them referred to as EPs....
Thematically Act of Depression dealt with the hatred of horrific acts such as rape, murder, and suicide. Cries of The Past dealt a lot with love, loss, and death.
They're both as preachy as any other Underoath album. What would you expect? It's a Christian metal band comprised only of devout Christian band members as it always was. Look at Disambiguation, it's like a testament to Spencer's recovery from various afflictions like his drug problem, and how his faith helped to guide him.
I could see it if you didn't like the execution of these two releases, but keep in mind their ages at the time. Pretty sure Aaron was 16. Dallas was 19. Not sure about Octavio or Corey Steger. It's no surprise the lyrical content wasn't as well executed as on later releases. The musicianship on these albums is totally remarkable, given their age and experience.
To say it's unbearable because of a level of preachy lyrical content not found on their other albums is a stretch. Act of Depression has two songs that give you an argument, Burden In Your Hand and Spirit of The Living God are awfully preachy. Set them aside and both albums are a black metal version of normal Underoath material in my opinion.
