Episode is indeed a big step for Stratovarius. It's the album on which they finally reached the sound that would last for years. So everything seems to be all right, except for the fact that Episode doesn't work so well as a whole. There are perfect hits like "Father Time," "Will the Sun Rise," and "Speed of Light," but the rest of the material fails in comparison, as is isn't as catchy or well put together. But despite these small lacks, Episode is very enjoyable. Each member of Stratovarius is a virtuoso of his instrument, and ever since Fourth Dimension they've played very well together. The best thing, however, is the diverse sound, which compensates for the lack of good songs. So, if you enjoyed the last two Stratovarius albums, you will love Episode.
