Still Life sucks. Morningrise is fucken excellent, I don't like any of the other albums (well the first album is still very okay). After Morningrise came a few boring albums with just a couple of good songs (April Ethereal, Credence), then came our Porcupine Tree fella Steve Wilson who tried to make Opeth sound like an 'aggressive' version of Porcupine Tree. Aweful.
I like PT a lil bit, but I don't want a producer to fuck up a band by making it sound like his other band. I do even like a few songs of the last few albums though. Harvest, Drapery Falls and Windowpane are nice.
