To be honest, though, the Belgianness of this story is a bit disappointing. As with the last Belgian Who story I encountered, we are merely a place where a battle between other tribes of humans is interfered with by non-humans and there isn't a single Belgian character in the play. (And yes, I know we didn't become independent until 1830, but the characters here are English, French, Daleks, Davros and the Doctor.) And geography is rather telescoped - one gets the feeling that Wavre is just around the corner from Waterloo, whereas it's a good half-hour's drive even on today's roads.
This is mere technical quibbling and whining of course. This is really one of the better aliens-will-change-Earth-history stories. It's also unusual for a Dalek story to try and take us inside the minds of the creatures. Colin Baker and Terry Molloy get called upon to deliver a lot more than usual as the Doctor and Davros, and rise to the challenge very entertainingly. And new companion Flip, played by Lisa Greenwood, is a great contrast both with Baker, who she seems to have an instant rapport with, and with the unspoken presence of Billie Piper's Rose, who shares a number of narrative points with her. She also has a good exchange with Molloy about Davros and disability, which is a strong sub-theme of the piece. It's rather a delight to hear her in action, though a bit sobering to reflect that as far as I can tell she had not yet been born when Colin Baker was the Doctor on TV.
I see that Terrance Dicks brought the Second Doctor to Waterloo as part of Season 6B, and look forward to getting to grips with that too. But for now, while this story may not completely satisfy Belgian perfectionists, it's rather a good new lease of life for the Sixth Doctor.
