I must confess, first of all, to not watching the entirity of this 'adventure'. I got through the first episode somewhat scathed but in one piece, but as the Menoptra started talking in episode 2 I realised that I simply couldn't do this. And so, in order to maintain my somewhat childish mind, I discovered the rest of the story via The Doctor Who Guide, and I discovered, somewhat unsurprisingly, that my course of action was probably for the best.
This serial is insane. I'm guessing watching it while drunk is the only way you'll get through it in one piece. But one cannot fault the people behind the programme for not only having the balls to try something like this, but for having trhe skill to pull it off as well as they did, given the limited resources of the time. Having seen the sets and the costumes, I have to admit for the mid-ish sixties, they did themselves proud.
The story, on the other hand, is something altogether different. It's insane. You have the Animus, who basically want to conquer the universe (starting with Earth, how original). You've got the Menoptra, who want to stop them. Then you've got the other races - the Zarbi, who are utterly useless (they're pacifists, see), and the Optera, which are irritating. And nothing makes any sense. There are cliffhangers which are resolved almost as pathetically as in The Age of Steel, there's characters which give you a headache every time they speak and there's dialogue that leaves you wondering what the heck the writer was thinking.
It's really not recommended viewing unless you're drunk, stoned or both. But if you are, go for it. You'll have a blast.
The Bumper Book of Made-Up Doctor Who Facts has this to say about The Web Planet: The vast majority of the props for this episode were made by the children of the production team, who had been forced to hold a makeshift creche after 'Treasure Tots' was forcibly shut down by police.
