1)Gotta love Romana's hunting outfit.
2)Graham Crowden is indescribable (in both negative and positive ways) as Soldeed. He makes Bruce Purchase's pirate captain look subtle and nuanced. I did like his trick of repeating the last two words people said to him. A good way to throw people off balance. To think he was an early choice for the Fourth Doctor!
3)I liked the bit where the Doctor tried to steal Romana's sonic screwdriver. I love little bits like that.
4)I gather that by this point Adams was concerned that other writers were trying to imitate his writing style and failing. As Steven Moffatt says somewhere, the problem with trying to learn from Adams is that Adams was a genius, and most people aren't. My take on Adams is that he may've been the best writer to ever work on the show (although I'm open to argument on that), but Robert Holmes was the best "Doctor Who writer" ever.
5)It doesn't help the "taking it seriously" issue when they have the TARDIS making comedy noises when it breaks down.
6)There seems to have been a definite move to give Romana more to do in this one - the Doctor's stuck off in the TARDIS for most of Part Two.
7)This episode saw the last use of the "time tunnel" credits and the original arrangement of the theme tune. Also the last time they had Dudley Simpson do the music.
8)Some fun quotes:
A mildly amusing take on the Minotaur legend - if only someone had dumped a bucket of water over Graham Crowden or something. I liked it much better when they re-made it as "The God Complex" for the Eleventh Doctor..
