Not an instant hit in the face, but it certainly grows over time. I find it to be a very solid album of theirs, although not their best. It is different compared to their other stuff, which I guess is why fan opinion is split about this one.
My favorite DF album. They still have a few classic style Dragonforce songs, but they also tried some different things, like slower tempos. Seasons is quite possibly my favorite song they've ever made.
