"Meglos", as I was hankering for a seasoned cheese sandwich, season 18, and a cheesy story.
At one point, deemed season 18's worst story in various polls, it's still weak on a narrative level and especially alongside season 18's other stories, the bulk of which don't make so many plotting goofs... But, heck, there's more to a story than mere in-story logic and use of real-life entities or ideas; it's great fun and lovely to sit back and just enjoy.
The music definitely suits the story.
Jacqueline Hill simply steals the show as Lexa. A huge fan of the Hartnell era, I'm not distracted by "BARBARA" at all, actually. That's just how good Jacqueline's range was.
Tom also excels as both the Doctor and Meglos. Would have made a fantastic Master, for which, given all the meta jokes the 21st century show has had, you know there'd be a field day aplenty with those.
Brotodac and Grugger are an excellent double-act, with some sparkling dialogue and great acting.
The two main Savants, Caris and Deedrix, are
okay. But so much of the story's dialogue is biased in their direction. It really was Jacqueline who gave Lexa any depth, and it would have been easy for an actor to have made Lexa insufferable.
Edward Underdown was said to be ill at the time, so the performance is forgivable, but not knowing that, there's no way to figure out the flat performance. Considering illness, he held up well under the studio lights and a fair amount of dialogue.
The Savants, and even more so for the Deons are largely 2D stick figures.
Obviously, issues about anti-clockwise rotation being taken seriously by the Doctor and Romana when the Earth also rotates anti-clockwise*, surprisingly generic names like "Dodecahedron" when you consider the effort looking up "chronic" and "hysteresis" within a big 1202-page thesaurus of the time, and how Caris and Deedrix are babbling theories and wishing they knew the size and composition, despite already knowing the big lump can't be moved... yeah, this story deserves its low ranking in terms of loose storytelling, but the production and pace, adornments like the music, some fun dialogue from various factions, and enough good acting do help it improve that much more.
6/10
* unless they mean it rotates in the opposite direction, meaning any clock you have running will be going in the opposite way, probably. A shame we never saw an orbital shot of Tigella where the planet is rotating from east to west... or west to east, depending on which direction you're looking at, particularly if you're looking at it above from one of the poles, which is why you always look down from the North. It's all relative and every planet's got a north...
