It's a toss-up between The Web Planet (the concept's not bad, but if I never hear the ssssslowly talking bugssssss again....) and Frontier In Space, in which nothing happens for at least 3 of the 6 episodes.
I hate those! About Time offers this comment on The Web Planet:
"If everyone on Vortis acted as if this were their natural environment, and as if butterfly-people were a perfectly normal part of the terrain, then after an episode or so we might forget the weirdness of it and treat it as a place where interesting things might happen. Instead, we get showboating programme-makers constantly shouting 'look, this is alien!' at us. And we just want to shout 'no, it's stupid!' back at them."
