Personally, I could never get into them. And trust me, I keep trying. I feel as if I should like them because of the other bands I listen to can relate to them somewhat; but It just doesn't click for me I suppose.
Ironically, I am a fan of the progressive genre for the most part. Than again, overtime the "progressive" term has been thrown around way to easily. You can take two bands considered progressive and they wont sound anything alike.
I suppose I am more so a fan of the old school, original progressive. Pink Floyd and King Crimson and whatnot. I know there is a difference in rock and metal, but progressive metal and progressive rock sound completely different if you ask me.
Its almost like Progressive is simply used if a band uses odd time signatures, odd scales, non-standard song formats, songs that easily go to 8 minutes, etc etc.
Rant rant rant! I can go for days *sigh*
