It's true that from 1980/81 onwards Dr Who's stories did tend to get more complex but the show was attracting more adult viewers and had become something of a cult series that began to rely more on it's own mythology for stories. As a child myself, it wasn't the plots as such that I took notice of, just the action, the monsters and the overall style of the show - the scripts were there for the older viewers.
The next story on my Tom-a-Thon, Warriors Gate, is perhaps the perfect example of how the series had changed and matured. A very complex, imaginative and thought provoking script with superb imagery and a very surreal feel. It's a very atypical story, which is why a lot of fans don't like it. Personally, I find it's a story I have to be in the mood for - sometimes it bores me, I find it pretentious and confusing, othertimes I think, "hey, this is brilliant!" This viewing finds me ina less critical mood, although I still wouldn't rate it amongst my favourites, or even as one of the better stories of the season. The white background tends to make things look a little cheap, however the gateway sets are magnificent and generate a really spooky atmosphere. The visual effects are extremely good, from the mirrors that people walk through, to the coin frozen in mid air, characters running through the void leaving echoes of themselves, the close up of the spinning TARDIS in Biroc's eye and the effect of the ray gun bouncing off the mirror - the effects here really are inspired and light years ahead of what we were getting just a year earlier.
The whole story has a very odd atmosphere, the grim, doomladen tone clashes with some of the comedic moments, and Tom seems rather detached from precedings, as though he's thinking of being elsewhere (knowing he was leaving soon, this was probably the case). I find Romana's leaving scene very disappointing, as it's so sudden and rushed, and I would have thought she deserved something more memorable. We also say goodbye to K9 - sad but it really was the right time to get rid of him.
So Tom is now left with just Adric - don't worry Tom, you can foist him off onto Peter Davison soon!
Warriors Gate is possibly the only story I can never make my mind up about. It's unique and I suppose that can only be a positive thing.
