Weirdly common stock genre show plots:
Some members of the team get shrunk (and have to go inside someone's body)
All the male members of the team are turned into simpering idiots by pheromones and have to be saved by the female member(s) of the team and I guess this is feminist somehow
Everyone on the team is trapped in their individual worst nightmares and the episode is called "Fear Itself"
Someone goes all "Heart of Darkness" on an alien planet
Trapped in a VR simulation (but you can die for real!)
The team is brainwashed into serving in the workforce of some alien planet
Lotus-eater plot (everyone is trapped in an idyllic fantasy world)
One or more members of the team "de-evolve" into cavemen
Someone on the team "evolves" to have super-intelligence (and this is bad)
