"Inferno"? Hmm, well, for a moderate percentage of American viewers in the 1980s, it was the "first" of the Pertwee stories we could see. While all of the Pertwee episodes (except for "Invasion of the Dinosaurs" Pert One) existed, many of them were only available in monochrome. Several PBS markets were initially reluctant to air an adventure that would have to "flip flop" between color and B/W. "Inferno" was the earliest of the Pertwee serials to have all of its 7 episodes in color (at least as of the mid 80s), so that was how and when many fans first saw the Third Doctor.
Later, those markets (at least WFSU and Georgia Public Broadcast, GPB) changed their policies and air all of the serials, alternating between color and monochrome, but that did not change the fact that for many viewers, "Inferno" was their first Pertwee serial.
On the other hand, the story could have been a bit more "tight" if not for the inclusion of the "Primords", the green haired "werewolves" skulking around the drilling site. Personally, I feel they were added to adhere to some "mandate" that every DW story feature a "monster".. Had they not been added, I bet the serial might have run only 6 episodes, possibly only 5.
