Ultimate sad sack music dressed up in matching sweaters. The early stuff is cheeseball fun while the latter stuff is crushingly depressing and increasingly drug addled. Kind of like the dark side of drug-pop music to The Beatles' light side
You definitely need to pick and choose certain songs/albums/eras. They vary drastically from cringe, all the way to the greatest song (Surf’s Up) of all time and to possibly greatest album (Pet Sounds) of all time.
The Beach Boys are like the Beatles and Paul Simon in my life, in that they're just part of my childhood soundtrack. My dad played Beach Boys songs on guitar for us when we were little.
