Our son came around and started enjoying this story as it went on. There’s a gunfight in episode three, and then the inevitable bit where Tom Baker gets to play both the Doctor and Meglos and the two have the contractually-obligated confrontation that all adventure television doubles stories need to have. Our son did, however, suffer the huge cheat of the villain’s base not actually exploding. The visual effects team did that rotten cheat that they sometimes do of turning up the lights and the contrast really fast so it simulates an explosion without actually blowing the model to pieces.
I think that “Meglos” would be the last time that Doctor Who would be quite this by-the-numbers for a little while. I think that the only real spark that the story has at all comes when Romana gets captured by the mercenaries and leads them around in circles, supposedly back to her ship as she’s been ordered. She feigns confusion caused by the planet’s anti-clockwise rotation and seems to be enjoying herself as she looks for an opportunity to turn the tables on the villains. Bill Fraser is also pretty amusing as the bad-tempered leader of the mercenaries, and these are high points in a story that doesn’t want to push any envelopes.
