In answer to the OP, no, I don't still LOVE Dream Theater. But I never "LOVED" them as my favorite band. They were A favorite (of many) for maybe eight years -- from when I first heard them in 1996, to about 2004. Then I gravitated away from them after not liking what came after all that much. I agree negativity sucks (trust me, I know all about that on a forum), but there's no way to avoid it and still have a communicative, vibrant, forum.
People have opinions, good and bad. It's how you present them that make the difference (as I've learned over the years). I don't really care for post-ToT Dream Theater much, but I'm still a fan, and still check out what they do. I skipped the last two tours, but saw them on the ADToE opening night (I think) at the Warfield in San Fran. I'll probably see them again if they come around next year on the I&W anniversary tour (again, IF it ends up coming stateside).
So I'm still a fan, but no, I don't "LOVE" Dream Theater. I respect them, and enjoy their work and seeing what they do. But I also like to think that I'm pretty intelligent (pipe down, bosk1 - lol) and open-minded, and like a place where I can discuss my opinions on the band, which may differ from the majority of people that "LOVE" them. bosk1 provides that place, and I'm pretty thankful for it.
