Episode 13 from season 20 this Doctor Who adventure originally aired here in the UK during February 1983, the fourth story from Peter Davison's second season as the Doctor & the second story from the Guardian Trilogy which started with Mawdryn Undead (1983) I have to say I really didn't find much here to enjoy. The one & only Doctor Who serial to be directed by Mary Ridge & one of only two Doctor Who scripts to be written by Steve Gallagher not that much has happened, usually most Doctor Who stories start of very strongly with an attention grabbing episode & start to wane but Terminus has started off badly full stop. I can't quite believe how much time is spent in this episode showing people walking around corridors, it starts off with Turlough & Tegan walking the TARDIS corridors, then it show's Nyssa walking around the spaceship corridors at which point the Doctor starts walking around the same corridors trying to find her & then annoyingly Tegan & Turlough join in the fun as they too end up wandering around the same corridors for not entirely apparent reasons. There was nothing in this episode to make me want to watch Part Two, there was nothing that really grabbed me, nothing that drove the story forward in an interesting way & the even the cliffhanger ending felt lacklustre. Terminus was Nyssa's final story as a regular companion & I can't believe she is so weedy as to crouch down on the floor in a ball when she hears footsteps, has she not faced the likes of Cybermen, the Master & various other evil aliens? Why not try to hide if she was so afraid? Why crouch down in a position that would have been in plain sight of everything that bothered to walk that way anyway? The other annoying aspect of this episode was the relationship between Tegan & Turlough who spent the entire time bickering.
Industrial action at the BBC by it's electricians meant that Terminus had one less studio day than was normal, with no location work apparently the atmosphere was not good on set. Production wise the sets here are very bland & grey in all senses of the word, the spaceship model shots are acceptable if underwhelming & the two space pirate outfits are embarrassing especially their huge over-sized oddly shaped goldfish bowl style helmets while their flimsy Lycra skin tight body stockings & capes don't help. There were no alien monsters in this episode & with none in the previous story Mawdryn Undead that means there's been a whole five classic Doctor Who episodes in a row without a single rubber monster suit.
Terminus: Part One is a distinctly underwhelming & dull start to Nyssa's farewell adventure, for me it just seemed like twenty odd minutes of groups of people wandering around incredibly dull corridors which in reality it was.
