Journey: One of the most disappointing albums ever. After In the Woods, I expected more than this dross. This is absolutely dreadful, uneventful, and horribly boring music.
Light of Day: Decent, but ultimately unsatisfying. I liked it for about 10 listens, now I can't stand to listen to it all the way through. I wish it had been divided into songs as one 60 minute track is probably the worst musical idea I have heard in that you cannot fast-forward to the good parts or past the bad ones (such as that horrible part with the female vocalist). If you could skip the bad parts, it would be a much better album.
I haven't heard the newest, so I can't comment, but I haven't heard really anything good about it yet.
I would not call them doom metal whatsoever, more like progressive metal. They don't have that doom sound, and they are not really depressing at all. They instead have a very noticable lack of atmosphere, emotion, and mood, which is why I find them to be so mundane. Omnio is at least 1,000 times better than all Green Carnation put together, easily.
