Oh come on, that's just bull****. As much as they sucked in the last 5 years or so, they are basically the band responsible for Progressive Metal to have expanded in the first place. Clearly you're searching for something else in music, and I can understand that, but try not to forget the fact that they've had a huge influence.
Plus, in my opinion, Image & Words and Awake are some pretty freaking good albums.
I agree on Mike Portnoy being overrated though.
