I like a lot of "flowery" albums but that is one of my least favorites of the "big" ones from that era-"Revolver" on the other hand is absolutely ace but it's more proto-flowery.

As for "Their Satanic...", I didn't know it was highly rated to begin with so I can't call it overrated really. Then again, it might be one of those albums where "everyone" has started to point out that it's not that bad (its status was that of a total disaster for many years) and actually pretty good and that has arguably made it overrated. If anything, it's something of a cliche to call it "underrated" today. For me, if viewed as a "Sgt Pepper..."-ripoff disaster, I think it's underrated, if viewed as a good Stones-album, I think it's overrated...
