Uhura should have never been let out of sick bay after it was shown she had similar symptoms to the engineer from the space station. Then they LET HER HAVE A PHASER?!?!? WTH!?!
Kirk and Pike made some seriously poor command decisions. Or I should say the writers made some bad decisions for them.
Outside of that, I loved this episode. I also like Kirk mentioning Spock was about to be checkmated by Chapel. Nice touch.
