Oh goody! Only the true crap episodes remain, woohoo!
I have to vote to save "Children". Only because the writers really went for it, despite a lot of misfires in this story, but succeeding in selling some momentous occasions - such as to have transporter technicians blissfully beam people out into space and so on, and all on top of using the crew's fears against them as psychological horror that even Hitchcock might find worthy of some time, even if those amount to cliches. (if nothing else, seeing Kirk act all paranoid is surprisingly effective. Shatner genuinely is an underrated actor, especially as he took the cultural zeitgeist that followed into a new act in of itself. He's that good.) Besides, "Children" has the acting talents including but not limited to the voice of Peanuts Lucy (who also played Sally Simms), plus the dude who invented that cool instrument used in "Star Trek The Motion Picture" who also put his ciggies into Greg Brady's bookbag. \
to compare, what does "Alternative" have? At best, it's an early example of using a theory of parallel dimensions, but that's why people watch the entertainment: What they do with the concept, not just the concept in of itself. It's like looking at a window, and few people care to know how a window is made. But that's another story, best suited with tons of needless and distracting music, camera angles changing wildly every 1.3 seconds, and so on, because otherwise it's apparently not exciting. Unless your job is to craft windows or anything made from glass, then all those distractions probably aren't as good, I guess...
So, ultimately, what does the "Alternative" episode have? IMHO, not even crickets, unless they're snoozing deep within the Vasquez rocks where the story was filmed. or the lizards basking on the rocks' surfaces. They may have even inspired the Gorn at one point...
