Well, yeah, the Nimon are actually fairly decent baddies with A Plan, and they go about it in a pleasingly underhanded way. Them looking cheap/daft is not, in my opinion, a legitimate criticism since they probably made the story on about £2.50 (and that all went on Tommy B's drinks!)XD

And, as you point out, the main thing the story has is Romana being, as the fanvid on YouTube reminds us, Awesome. Especially that bit where she's going mental at the spaceship pilot: "You despicable worm!! Turn back - NOW!!!" And she does that angry-Romana face as she's shouting at him. Excellent. :)
