After his death, Richard Burton wakes up on an alien world — along with every other past inhabitant of Earth (although not necessarily in chronological order). I found the concept more interesting than the execution. The world is brutally simplistic by design, so the complexity has to come from the character interactions, but even with a complete cast of historical figures to draw upon, I didn't think this really went anywhere worthwhile. (Goering, honestly? Perhaps in 1966 this seemed like a better idea.) Not a series I'm likely to follow.
