Jim , I have been reading your posts and I don't get your opinions on almost anything. Firstly, It's the album most affected by Brian's maturation not his illness. He was expressing his deepest feelings of love and life from the heart and mind of a 23 year old man. There made be a few sad or bittersweet songs, but depressing it is not. The songs are a far cry from being mediocre, if anything they may be innocent, and that is only from todays perspective, 40 years ago they were poignant. Lastly, The Beatles were a worldwide phenomenon, far more popular than anyone on the planet with far more influence than any other musical band at that time. In my opinion, Sgt Peppers was a step ahead of Pet Sounds, however, because of their popularity, the Beatles probably could have put out another album similar to Rubber Soul and still outsold the Beach Boys, such was their worldwide appeal!
