Okay, it was on a fortnight ago, but I thought I'd bring it up now, anyway. Stargate SG-1 recently celebrated its 200th episode. The plot was pretty much a retread of its 100th episode, but instead of a fake TV show based on the Stargate programme, the show brought back Willie Garson (Stanford from Sex and the City) to mess around with ideas for a fake Stargate movie instead.
Writing it down like that actually makes it sound like it had more plot than it had, since it was really just an excuse for the show's producers to take the piss out of Stargate, other sci-fi shows and movies. It had all been done before and much better by that 100th episode I mentioned earlier, as well as (of all things) the Hercules: The Legendary Journeys episode Yes, Virginia, There is a Hercules, in which the cast played very unflattering versions of the show's own production team (with Bruce Campbell playing an hilarious version of Rob Tapert, his real-life lifelong friend).
So I won't dwell on it too long, except to mention that Richard Dean Anderson (MacGyver himself) made a welcome return appearance as Jack O'Neill, although most of the time as a puppet.
And there was also this rather good parody of Farscape, a series that starred Ben Browder and Claudia Black, who are both now stars of Stargate SG-1. Anything that mocks Farscape (or as we know it in our house, “The Silly Show”) has to be good as far as I'm concerned.
Just as a little background, Vala (Claudia Black) is busy suggesting ideas for films that she claims are based on her life, but are actually things she's seen on the tele.
