Will Brooks’ 50 Year Diary - watching Doctor Who one episode a day from the very start... 

Day 383: Invasion of the Dinosaurs, Episode Five

Dear diary,

I’ve seen it said that the thing which lets Invasion of the Dinosaurs down - even more than the titular monsters - is the story involving the ‘spaceship’. The general consensus seems to be that this entire strand of the plot lets the story down somewhat. It’s perhaps true that it’s not where you’d expect this story to go having watched that brilliant first episode, but at the same time I’m not sure that I take any issues with it.

For a start, I really do like the design of the spaceship itself. It’s very 1970s in places (and Emma, sitting in on this episode with me, was quick to point out that being kidnapped was the last of Sarah Jane’s worries, and that she should be more bothered by the double denim outfit that they’ve clothed her in. I didn’t have the heart to tell her how much I actually liked the costume…), but it works. It’s a nice design, and it stands out well from the other sets in the story. They’ve very cleverly kept the colour pallets for the ship and the underground base at opposite ends of the spectrum - you really do feel as though you could be somewhere else.

And it’s a chance for Sarah Jane to put her reasoning to the test again. I loved her during The Time Warrior, as she tried to work out where she might really be, and it’s good to see her doing a similar thing here. It’s clever that the injury on her head leads to her realising so definitely that something is wrong here, and her daring to use the airlock to escape is rather fun, too. It’s not all good news for her, though, as she heads right back to UNIT’s temporary HQ and admits that she knows everything to General Finch, before confirming that she’s not spoken to anyone else. Oh, Sarah…

Though, in fairness to her, there’s really no one that you can trust in this story, is there? Finch… is working with the bad guys. Sir Charles Grover… is working with the bad guys. heck, even dear old Mike Yates (who Sarah’s only known about as long as she’s know the other two men, but we’ve known for a few years by this point)… is working with the bad guys! It’s not often that the Doctor and his companions find themselves in such a tight situation, but it’s great fun to watch.

It also means that we get to watch as the Doctor’s friends are turned against him. We’ve known for several episodes now that Yates is working for the other side, but seeing the revelation from the rest of our regular cast is wonderful. The Brigadier is helpless to act (cleverly, we’ve been reminded in every episode that Finch is in charge and can over-rule any of the Brig’s decisions), and watching Yates be so stern with the Doctor is somewhat heartbreaking. Thankfully, it’s offset by a lovely scene in which Benton allows the Doctor to overpower him and escape (and that scene sets up a fantastic line when the Brigadier has been ordered to arrest his Seargent: ‘Well, Benton. Go and put yourself under arrest!’).

The fact that so long is given over to - essentially - a prolonged chase sequence should irritate me. Nothing’s really happening, it’s just filling time, but it feels somehow so right. Chases down country lanes, a helicopter… I know they’ll be doing something similar by the time we reach Planet of the Spiders in a couple of weeks, so it may not fare so well with me that time around, but it’s great for now. It also gives us some beautiful shots of the Third Doctor hiding in the woodlands. Though I’ve seen the story, I’d completely forgotten these images, but they’re stunning. Some great direction here.

And now… well… I can’t remember where we’re going, either. I can’t recall what actually happens at the end of this story. Do they blow up the base? Arrest everyone? I really can’t remember, and I can’t wait to find out…
