The Crystal Maze/WMG

The contestants are all trapped in purgatory

That's why they consistently display Genre Blindness and Too Dumb to Live tendencies - they're dead, which throws off their minds a bit. The capricious, Nintendo Hard nature of the Crystal Dome is the final and worst of their trials - those few teams who succeeded made it to Heaven. (This is also why the children's teams always win the prize - i.e. go to Heaven - even if they fail; Children Are Innocent, after all.)

Richard O'Brien is The Doctor

Let's see:

• Rudeness
• Companions
• An awful lot of running (including hand holding)
• A strange dress sense
• Manic behaviour
• Smug Super attitude
• His harmonica seems like a replacement for his recorder

To say nothing of the strange alien theme park setting...
