Oh, not the Bobby stuff. In fact, I first realised I was developing a 'take it or leave it' attitude about SPN when Weekend at Bobby's was the high point of S6 for me.

There was just nothing that grabbed me about S7, even though I kept trying. The only thing I specifically dislike about the later seasons (not that SPN is alone in it, I've stopped watching other shows I was less invested in because of it) is the intrusive background music that has turned up more and more since they lost actual music. Overall I think it's just been a gradual decline of interest for me.
