Zombie Hemmer was freaky! Nicely done, wardrobe/makeup.

This clearly took a lot from TNG's Night Terrors right? A bit of Firefly's Bushwhacked in there too.

I liked it overall, but my favourite Star Trek episodes are when the crew gets to use their extreme competency to overcome a difficult challenge. This episode, the crew was... not so competent.

• Una's team can't identify that there's been sabotage even though it's just like, phaser blasts from a half-deranged man
• The dude easily escapes from sick bay and blows up a nacelle (had the stun setting not been invented yet? What about locked doors?)
• There's no way the medical team could keep Uhura around and try to do some tests when she's having an episode, they can only put on the brain scan screensaver
• They can't shut down the dang refinery! The lever's stuck and they're out of WD-40!
• Pike blows up the quadrillion dollar infrastructure project immediately, not even just targeted laser blasts to the parts that are doing the murder. The whole thing has to blow up.

I guess this is just trek being trek and I shouldn't take it so seriously. Emotionally, the crew was at the top of their game: intuitive, perceptive, empathetic, trusting. good stuff.

But yeah, I feel like I would have enjoyed this more had the problem been made more difficult instead of the crew less capable.
