Query: "I've waited a long time for this!"

After "The Deadly Assassin", there always seemed to be a story or two in a season that helped fill new Gallifrey/Time Lord continuity. "Underworld" is one of them. Giving us the explanation of the Time Lords' noninvervention with other peoples and planets. That's the interesting bit. The rest is a mix of sloppy extras acting, repeated scenes of guards walking and running up and down and some bad CSO that hadn't been seen since the Pertwee era. There's a neat premise with the Minyons looking for their long lost race bank so their culture and people won't disappear. Their race bank is hidden in the middle of the newly born planet protected by the insane computer, the Oracle. Sounds decent, but it just moves at a snail pace. And besides the interior of the Minyons spaceship, it has a REAL cheap feel to the production. Still, there is some humor to help, and the leads, Baker and Jameson are consistent.
