Rate: "The Krotons"

At a certain time every year, the two brightest, smartest Gond youths are chosen to disappear into the bowels of a machine and join the gods of their people.  Or at least that's what everyone thought until the Doctor, Jamie and Zoe arrived, and discovered that the "gods" were nothing more than aliens with a crystalline structure who called themselves Krotons, and who feed on the mental energies of the children.  Worse, it seems that the Doctor and Zoe are now on the menu.

So what did you think of the Krotons?  Here's your chance to have your stay.

Tried watching this one again recently. I wanted to like it, I really did. I didn't, unfortunately. It's just dull and the Krotons themselves are awful. 1/5. And I don't like to think that any Troughton is bad.

A shoe in for 5/5. Sublime genius story.
