Here's my thought, Naylor needs to let someone else direct and let them have some say. He has ideas that he can't pull off, and is shows. The dancing robot scene in season 8 for example. A good director would have insisted on cutting it down to a manageable size. Season 9 had similar issues like the extended "writing scene" where Lister takes over the typewriter and controls his shipmates. That was a good gag at a third the length.

I know nothing, I see nothing, I wasn't there,
and if I was there, I was asleep.
