Hmm, TNG Season 7. There's probably no other season in Trek with the same crazy mix of really strong episodes and what-the-fuck-were-they-smoking episodes.
Ronald D. Moore recalls about the writing of "Interface" that the writers looked around at each other and basically said "This is sad ... this is the best we can do?" For a while it seemed like every episode was "let's see what random weird shit we can have happen to people."
"Phantasms," "Dark Page," "Sub Rosa," "Masks," "Eye of the Beholder," "Genesis," "Emergence" ... all head-scratchers. But I'd rank "Gambit," "Parallels," "The Pegasus," "Lower Decks," "Thine Own Self" and "Preemptive Strike" as among the show's best.
"Genesis", really? Talk about random, bizarre stuff happening to the crew. I mean, it's not a terrible episode but it's endemic of the problems the franchise was starting to have, in particular due to Brannon Braga who just wanted whatever-the-fuck to happen without thought to what it means to people.
In Genesis we have an absent-minded move by Crusher to cause the crew to "de-evolve", which seemed like a rather "easy" accident to occur, and it doesn't seem like the writers considered how stuff like this would impact real lives, including civilians and children. Instead at the end we have Crusher, who was mortally wounded and needed reconstructive surgery, and Troi laughing over Barclay's insecurities. Ha, ha! People died.
And tell me how people who devolved into beings with smaller brains regrew the knowledge and skills lost when they returned to normal. Brains don't work like that! Evolution doesn't work like that!
The episode is a pure mess.
