Seriously how can I like this post about a hundred times.If there was a way to delete the Booker/Tarka storyline, this arc could be one of my favourite Star Trek stories - even if it's just a take on Arrival.
I get the mad scientist thing, but the fact that everyone else just goes along with him when he's so obviously on the wrong side just makes it so frustrating to watch.
If this episode was just a communication story and seeing how the crew deal with stress, it would be an easy ten for me. The Tarka subplot, the missing Reno, ect really weaken the episode. I don't know if I can give the episode an 8, and it should be so much stronger.
