I thought the episode where they were all inhaling the psychotic drugs on a planet's surface was pretty weak. Basically, these 23rd/24th century people strike me as being competent at running the machines at their posts (when they work) and eating food at the canteen, but throw them into the wild and they start bugging out. I guess that's what society is coming to anyway.
I think they need to have an episode where the entire crew gets ripped off by some wily natives like a bunch of unsuspecting rubes, like exchanging some critical fluid to run the warp drive for WD-40. Wait, did they already do that episode?
