My appreciation for the Doors stems from the fact that while they were "trippy", they put out some really good music, and showed great musicianship. Each member was extremely talented and good at their craft. Even when they'd play some very trippy stuff, and Jim Morrison would be extremely wasted, they still sounded great. Jim is one of the few singers who could make drunk gibberish sound good.
Yeah, they are a little pretentious, but what 60s group wasn't pretentious?
Robby Krieger, Ray Manzarek, and John Densmore are musicians that people tend to overlook. Jim didn't want to be the focus of the group, but the singer always gets the attention.
