Name the episode that in your opinion starts out Fast and Furious, but ends up Slow and Tedious.
"Miri" for me. The teaser is one of TOS's very best, and ends on the provocative question of exactly how a duplicate Earth could exist. You're really dying to find out how this could be possible. And then the episode itself takes a left turn into a story about the Grups and the Onlies, with no explanation ever offered for why this planet is an exact double for Sol 3.
When the answer turns out to be "'Just because, okay?", why even raise the question?![]()
That's exactly why I dislike the 'parallel planet' episodes. They are just too ridiculous to explain.
You guys need to read more Hodgkins.
