You sir, are an idiot. First off, Robert Plant is one of the greatest male vocalists in rock history, up there with Freddie and Roger. His unique voice is an essential part of Led Zeppelin. Secondly, is there a reason Jimmy Page is referred to as "one of the greatest guitarists in the world"? Yeah, it's probably because he has a lack of imagination and covers that by playing loud. So before you rag on the forefathers of hard rock, get your facts straight.
