Honestly how many shows in a season need to be enjoyable for people to have a good time? I'm only actively watching Jojo's and Ping Pong (I'm super behind on Mushishi and Captain Earth but I intend to catch up on them) and those two shows are GREAT. In general, anime or not, most of everything is shit. If I can find a few shows per season I enjoy, which I usually don't have a hard time doing, then the season is doing fine as far as I'm concerned. Even if a season had a hundred shows and only one was good but that good show was AWESOME, I'd consider that a success. I guess people need anime to fill in every moment of their free time?
On an unrelated note, despite everybody saying the Fate/Stay Night source material is awful I will continue to have hope that the show will be great #BELIEVE
