Completely over-the top... I've seen more WWW episodes than I care to admit. At its best, it's a guilty pleasure. At its worst, it's profoundly stupid. It works well when it sticks with more-or-less conventional villains looking to kill the President, or cheat settlers out of their land, or print counterfeit money (etc, etc, etc). It works badly with super villains who seem to have been dragged in from a James Bond film. (Why do you think the hero is named James? (The writers apparently never had the nerve for him to introduce himself as "West. James West.")
The chief of these villains is Dr Miguelito Loveless, a scientific genius whose plans vary from honestly trying to help people, to just being mean for its own sake -- and sometimes a mixture of the two. A dwarf, he's played by a real-life dwarf (not a midget), the superb actor Michael Dunn. Superb is not too strong a word. Put him in a scene with anyone, and he steals it, simply by the intensity of his personality. *
Of the "crazy" WWW episodes, this is arguably the best, with a complex story that wouldn't be out of place in James Bond film. The basic plotting involves Dr L destroying forest life to make the Indians dependent on him, a prelude to destroying Washington and giving the country back to the Indians. And that isn't the half of it. You have to see it to believe it.
The budget for this episode must have been huge, involving large, complex sets, and two versions of the same Indian village, one outdoors and the other on a sound stage. The producers must have thought "This is a great story. So let's throw money at it." And they got their money's worth.
* I can't help but think of Dunn in "No Way to Treat a Lady", where he confesses to the murders. The police dismiss him, and he accuses them of prejudice towards small people. "You don't think I'm big enough!"
