S11: Invasion of the Dinosaurs: Ropey effects, but quite fun and with interesting plot
24 May 2015 | by (United Kingdom) – See all my reviews

Returning to London from the Middle Ages, the Doctor is sure he is not too far off the time that he and Sarah Jane left, but an abandoned London suggests he cannot he right. Encountering only looters and hooligans, they seek out the support of a passing military patrol, but find themselves under arrest as looters and are sentenced to a detention camp until such a time that a civil system returns to sentence them properly. Meanwhile UNIT have little time to be trying to deal with the looter menace, since a much bigger threat to London is randomly attacking before vanishing without trace.

The Time Warrior was an enjoyably brisk start to the eleventh season, and it was with some doubts that I saw the next serial was back to being a fuller 6 episodes – which often means that a 4-part story is delivered over 6 episodes rather than there really being 6- parts there. Despite this, I really quite enjoyed Invasion of the Dinosaurs, despite the obvious weaknesses that it has. It is a sort of game of two halves. In the first we have the focus being on an abandoned London (the novelty of which is increased by having the Doctor bazzing around the streets in a souped-up bumper car), and of course we also have the dinosaurs. In brief glimpses and far-off shots, the effects are not too bad – indeed the opening episode I saw was only in black and white, which masked the effects and gave it a horror-feel; however the more it shows and the more it tries to do, the more laughable they become. There is still a certain amount of fun to be had with them, but it is hard to avoid that the T-Rex looks like a terrible plasticine version of Homer Simpson in his Tracey Altman days. The plot around the dinosaurs in particular fills a few episodes, despite recycling the same cliffhanger at least twice.

This gives way to a more interesting plot, which is a bit over the top perhaps, but allows for the idea of "greater good" rather than just being pantomime villainry. It is perhaps not a moral issue that is debated or poses a real quandary, but it is an interesting change to the usual plots, and it is a welcome and unusual find to have such a narrative mixed with the dinosaur action. This being 6 episodes, there is still too much padding around the edges, but generally it works and the cast have good fun – Pertwee enjoying his wry moments and action moves, while Sladen makes good on the script giving her plenty to be involved in, and lead on in some cases. Frankling delivers a good turn as Yates, while Courtney and Levene are both solid. The support cast didn't totally make the most of the material, but generally are okay.

Not perfect by any means, but for its flaws it is entertaining with some interesting elements in the plotting, continuing a very good start to this season.
