'Emanations' sucked but the themes and basic idea were very interesting. It's a shame it flopped. They really probably should have forced themselves to filter when coming up with an episode: 'Would we/could we have done this on TNG?' If yes, the next question would be 'Is it worth telling this story on Voyager?' an 9 out of 10 times, that answer should have been no. Only when the story was worthwhile should it have slipped through.
'Emanations' is important because it is (I believe) the first episode to reinforce my one rule of 'Voyager':
The universe hates Harry Kim.
When you accept and watch with this in mind, everything
about Voyager makes more sense. Seriously, try it.
