Seeing as the good points comprise a short list, let's get them done first. Martha continues to be good, although she did nothing in the second half of this episode but gasp with astonishment, and has also picked up Rose’s old tack of befriending proles.

David Tennant has stopped looking like Richard Hammond and now looks a chicken, which is mildly amusing. And the initial premise of setting the episode in Hooverville was almost interesting, but even that was soon smothered in class war nonsense, thanks to the worst writer since Mark Gatiss.

All of which are grand shits and giggles, but not when you are busy turning the Daleks into workaday pantomime dames. They previously delivered menace by sheer numbers and/or their unstoppable powers.

Now they’re busy making monsters so rubbish that not only could Torchwood probably take them out, but also completely undermine the faceless, unreasonable way of the Daleks. And it’s not as if they are doing so in a funny or interesting style.

The Cult of Skaro used to get stuck into slagging matches with Cybermen; now they are crushing humanity with humourless intent. The writer, so conceitedly merry at having created a Dalek/human hybrid and doing something with the Skaro line of thinking – in other words, putting fanwankery ahead of programme making - casually overlooked the need to write interesting dialogue.

Meanwhile, if the Daleks are trying to engineer minions to stealthily gather up humans, does replacing a human’s head with that of a pig really sound like an inconspicuous solution? Why not just replace their arms with toilet brushes, and paint them pink, Daleks? How does that sound? Christ, they sure are lucky humanity is so stupid.

Elsewhere, the accents were worse than could have been expected, with Talullah’s Betty Boop effort being particularly shameworthy. The attempt to make us care about a couple we’d seen together for literally a few seconds failed miserably; I couldn’t care less if any of the characters live of die. The big musical number was irrelevant and weird.

Plus, I’m taking back all the nice things I said about the CGI this series. New York looked like crap.

The original Doctor Who eventually lost viewers because it was too self-involved to be any good, and this episode went a long way down that road. With a script this irredeemably awful there won’t be five minutes of watchable content, let alone two full episodes worth. Next week: probably a review of Vernon Kay’s Gameshow Marathon instead. It can’t be worse than this.
