The topic today:
What is the most inane and unintentionally laughable Robot/Android related epidoes of Doctor Who?
My Choice: The Krotons
The TARDIS arrives on the unnamed planet of the Gonds, who are ruled and taught in a form of self-perpetuating slavery by the alien Krotons - crystalline beings whose ship, the Dynatrope, crash-landed there thousands of years ago after being damaged in a space battle.
The Krotons are at present in suspended animation, in a crystalline slurry form, awaiting a time when they can be reconstituted by absorbtion of mental energy. Periodically, the two most brilliant Gond students are received into the Dynatrope, apparently to become 'companions of the Krotons' but in truth to have their mental energy drained, after which they are killed.
When the Doctor and Zoe take the students' test, their mental power is sufficient to reanimate the Krotons. The Doctor discovers that their life system is based on tellurium and, with help from the Gond scientist Beta, he is then able to destroy them and their ship using an impure form of sulphuric acid. - Source: BBC Cult website.
First off, the Kroton props/costumes themselves. There are just too many shots where you really can tell the costumes are disintegrating under their own weight. They were oversized, and the actors within them could barely move. Beacuse of this, the script had to be hurriedly altered and some sequences cut because they just could not accomplish the tasks the writer intended.
The character development is also sub-par, but the Krotons themselves just stand out like a sore thumb, especially seeing as how most of the set design work in the episode is so bland and uninspiring.
A close second would be King's Demons, mainly because it was obvious from the get go that Chameleon was meant to win over K-9 fans, and the prop itself was so faulty and cumbersome, that adding Chameleon as a companion was going to be a royal pain.
Dishonorable Mention: Destiny of the Daleks
The writing for this one is pretty good, but K-9 was out of commission for the whole story, and the Dalek props were so beaten up from years of abuse and inadequite storage, it was almost impossible to take them seriously. This has got to be the weakest Dalek story, at least from a visual standpoint, in the series history.
Okay, folks... Flame away! ;-)
