They have incredibly good songs, good songs spoiled by bad parts and good parts in lame songs (glaring example: Innocence Faded/Awake - check the ending!). Oh, and I forgot "slow" songs, I hate most of them (Goodnight Kiss - aargh).
My fave albums are Awake and Falling into Infinity (accused of sellout, but has gems like New Millenium, Hells Kitchen, Lines in The Sand and Trial of Tears). Those, being my fave records of them, still would be better after work with Big Fucking Scissors

Train of Thought was disapointment to me - those solos are pointless and incredibly wanky in fact. Ending of "This Dying Soul" is just disgusting.
I hope their next effort will be more melodic, fusion-spiral-architect-goes-pop stuff - I like this side of them most.
