I suppose it depends on how we're defining worst, but I don't put reality tv, cooking programs, home improvement, shopping, day time court rooms, or anything like that on the list as those aren't trying to be good programming or good anything. I suppose the difference is between one being presentation and one being created and presented.
I chose instead based on the fact they'd intended themselves to be good, been created and presented with competence above that of zero and were still ****ty for a variety of reasons.
I don't mind when a turd is still a turd. I mind when a turd has the opportunity to become gold and for a variety of reasons remains a turd.
