"Galaxy 4", by William Emms, is a story that I expected to dislike. Perhaps it was the uninspiring title, the idea of the "cute" robots known as the "Chumblies", the shonky CD cover art or the presence of Steven Taylor, who I've never had much time for. Maybe it was a combination of all four. However, after spinning the first episode of the story into action I found it surprisingly enjoyable.
"Galaxy 4" has a slightly predictable and plodding plot, but within it is a mildly interesting study of prejudice and how one should never judge a book by its cover. Unfortunately, Emms' script lacks subtlety and the long speeches of the Rills become somewhat preachy by the end of the fourth episode. I also suspect that there is quite a visual element to the production of "Galaxy 4", as the long periods of Chumblie sound effects where Peter Purves' well-executed narration falls silent ably illustrate. Unlike a historical, where one can picture lavish costumes and sets, the audio "visuals" of "Galaxy 4" are rather sparse. But maybe that's a part of the arid setting.
The regulars play their parts well along with Stephanie Bidmead as the ruthless Maaga, although Steven isn't given a lot to do. Aside from that, the robotic nature of both the Drahvins and the Chumblies means that there aren't a lot of supporting characters to develop and it's left to the story itself to carry things along. And at that, I suppose, "Galaxy 4" is reasonably successful.
