Feels very much like a Pertwee story, but I guess that was on purpose, some familiarity to go with the new Doctor. It's great to have the Brigadier and Benton do a lot as we will start to see them a lot less from this point on in the show. Tom Baker fits in right away as the fourth Doctor, episode one he especially shines in. The villains are fine as is the titular Robot, although the graphics aren't good.
