Well, I certainly agree about "The Beta Cloud" and "The Rules of Luton." However, I thought that "Space Warp" was one of the better season two offerings, about par for what season one was or maybe even a little better.The brief schedule is:
January 75: end of filming on season one.
August/September 75: first UK/US transmissions.
October 75: Go-ahead for season two, on condition that an American is brought in as producer.
November 75: Freiberger writes a reformatting outline.
January 76: season two starts filming.
So it's a roll-through... Season one did well enough for there to be a season two, but TPTB wanted an American-led 'improvement'. Unfortunately...
Under the pseudonym of Charles Woodgrove, FF wrote three of the worst episodes of season two. They are maybe an indication of what he was aiming for. Or maybe just an over-worked producer writing anything that would be ready to shoot next week, to balance budget over-runs elsewhere.
My season two mini-review is here, and my season-one mini review is here.
