The Krotons are one of the Whoniverse's more interesting species, which is always a plus. Good incidental characters, another plus. How Sixie defeats the Krotons, though -- that is just the best!! ( )

The Krotons are, everyone will agree, not the greatest of Old Who monsters, but Return of the Krotons actually does a decent job of reconstructing them, fitting them also into the chronology of The Ark in Space and perhaps also The Ark. I liked the sense of the small group of people trapped by their own culture and by the growing alien menace which they won't comprehend. Nicholas Briggs does a great Kroton voice and also puts a bit more substance into the concept of the creatures. I enjoyed it. (And Charley gets to make the Kroton/crouton joke.) ( )
