Bill's involvement with SST in general has been minimal at best: I think Elmo's dad is the only character he's ever performed on the show.
I don't know if he actually disliked it or not, but I remember Frank talking about how confused and out-of-place he felt during the making of DC, mainly because he didn't understand why Jim felt it was necessary to bring him on as co-director (though Jim said he thought the movie would be better that way), because not only did he not really know what Jim was going for with the movie (then again, nobody really did), but nobody even came to him for insight/input anyway, they all went to Jim who did most of the actual directing anyway.
