I not gonna bother reading all 10 other pages of this topic.
I've seen a lot of really old bands mentioned who are respected for the influence they had in metal. That's all well and good, but I'd like to put forth a number of newer bands that I have seen little to no hate or bashing of, that may not be the oldest or hugest metal band around.
Windir. (Came around in the mid-late 90's, and is regarded as a class-A viking/folk/black metal act, and many people herald Valfar as a musical wizard in both life and death)
Atheist (These guys were around in the veyr late 80's, and only released 3 albums. 'Unquestionable Presence' seems to be considered a true cult death metal classic, and almost all their work is in high-regards. I have never seen hate on Atheist, though some people didn't care for 'Elements' which they considered too proggy and jazzy. These guys also influenced Tech/Jazz/Prog metal for the new generations of groups.)
