I dunno whether I am allowed to include crappy television programs, but I have watched, albeit voluntarily and recently, two of the worst
Doctor Who serials ever to be done:
The Ark and
Four to Doomsday. Admittedly, it was the first time I had ever watched either of them. It will also probably be the last.
The DVD trailers are much better than the stories themselves.
Here's the one for The Ark and
another for Four to Doomsday...
Actually, I've had an idea for a thread...
