KINDA the review
That's more like it. Mind you the Doc lets Tegan fall asleep against a tree and goes off, leaving her alone and then worries about her oh, almost 19 minutes later while talking with Todd. The guest cast is suitably well experienced and the acting is good. Tegan seems to want to go home, only. Adric is the Adric of season 18 again, thank goodness. He wanders off, makes good scientific guesses, gets in trouble (Oh and he shuts the door to the machine that starts it, so how is that any different to the Doctor's opening it in the first place?). The Doc and Adric ARE very much alike in many ways. And this story makes you think the two of them alone would be much much MUCH better than having the two girls along for the ride. The nightmare is perfectly creepy until the boring double act returns...why have a double of Tegan appear. It's such a cliche. I love the aliens who are named after and symbolic of Adric, the Doctor and Tegan. Perhaps the Nyssa and Adric ones are the missing crewpeople? And the Dukka is the Mara representing the evil side of the Doctor.
Peter Davison seems almost totally settled into the role and has some really good Davison-isms ("An apple a day keeps the ahh, never mind" and "there's no need to shout"). Adric is a great companion still and has warmth ("it's beautiful") and wants to be there. He also has some good plans for escape which the Doctor nixes here.
The mystery of what is going on is kept. People have vanished. There are two slightly unhinged males at the base and one female who is really quite good as companions go. And then there's the chimes, the Kinda who wear double helix models around their necks, the tree, the nightmare plain, and what is going on. It's all fitting in well with DW as a show again and seems apt to follow the greatness of everything from FULL CIRCLE TO CASTROVALVA. The regulars at least act like the regulars again and Tegan is still at odds with Adric even though he's perfectly happy to be with her or not directly talking to her face. Notice how she tries to help Nyssa beat Adric at draughts. She still doesn't seem to like him but he still seems to try with her, despite FOUR TO DOOMSDAY where she's just more of a moron than he is.
A good ep and even though studio bound, it feels outdoorsy. Well done. And a good cliffhanger...what will they do?
