Here we are again, back with an animated episode!
This is, in fact, the very first animated version of a missing episode. It’s kind of impressive the way it’s done. You wouldn’t think it would work out as well as it does, but clearly they spent a lot more money on this particular release than they did in subsequent animated versions (see: “Power of the Daleks“).
The slow buildup in this story is interesting. We don’t see the ultimate threat, the Cybermen, until much later in the tale (though we see a hint here). What we get in the meantime is what seems to just be a story about a sinister electronics corporation that’s hell-bent on…something.
And the corporation in question does seem to be fairly sinister, with armed thugs killing someone, a weird CEO (the way he says “Packer” is something I’ve always found interesting), strange computer systems and knock-out gas.
Really, it’s a great set-up for the rest of the story.
