Let's see...
Serenity Painted Death- like someone else said, first half a minute or so of riffing is just kind of meh and uninspired sounding, so are a few other riffs and melodies in the song.
Harlequin Forest- Eek. I love almost all of GR but just don't care for most of this song at all. If I had to pick out one single moment, it'd be the quiet guitar harmonics part, just by itself, then Mikael comes in and sings, "Nocturnally helpless..." Just sounds sooo boring and lame to me.
Burden- The ending down-tuned acoustic little bit. Just don't care for it, a bad way to end a good song.
The Apostle in Triumph- "IN THIS FOREST!! WHERE WOLVES CRY THEIR AGONY UNTO THE MOOOON!!!" Yeah, nuff said. Unfortunate, cause I do really love the beginning and ending of this song, it's just the middle that's full of cringe-worthy moments.
Porcelain Heart- The main riff when it gets repeated ad nauseum toward the end of the song, just is boring and sounds too much like the riff from TGC.
Master's Apprentices- I really, really like this song, I just think the "There is a..." section at the top is a bit too long and monotonous, otherwise an excellent song. As a matter of fact, Deliverance really has very few "bad" moments, it's an extremely T I G H T album, moreso than any of their others, even if it's not quite my favorite. (It's up there, though, probably 3rd place).
