I guess the closest thing I ever got to metal in any form or shape was Iron Maiden (KISS is NOT metal :P). I heard about Manowar and I've seen one or two videos, but frankly I never got the joke and I just think they are silly (yes.... I know.... coming from me....
)
By the time I sort of lost interest in I.M. I was into totally different kinds of music, mainly punk, and I really can't say I know much about this whole metal scene, let alone Manowar. So, in short: I have no particular opinion on that band (other than I think they're silly).
