I finally got Imaginaerum and have listened to it a few times. As I mentioned earlier, I'm not much of a NW fan anymore but was curious to hear this.
I think the album is pretty good but it's WAY too long - if the title-track, Storytime, Arabesque, Last Ride of the Day and the second half of Song of Myself were left out, this could be a solid album. There's still good stuff, though; my favorites are Rest Calm (which reminds me of Amorphis), Scaretale and Slow, Love, Slow. The more typical, safe NW songs didn't impress me that much but were ok. Another thing I have to criticize is that the guitars and drums aren't playing anything particularly interesting stuff, mostly power chords and basic rhythms, except on SLS. If there was no orchestra, these songs would sound quite hollow.
My album rating: 3/5
