I went 3 with it. It is alright, but when I think of the song the two parts that stand out the most are that descending riff (because it is an awesome lick) and the growled vox over the acoustics (because it is weird).
Must admit, the song on a whole has grown on me the more I listen to it.
It doesn't really stand out much as a section. The following part is probably far more memorable, and there are some seriously heavy and awesome riffs in this song that outweigh the slower section. The guitar melody is pretty nice though, but its "classic" Opeth.
