RIP Ensign Gamble. You knew what you were getting into.
I liked this one a lot - I'm generally a fan of "ancient, unspeakable horror" stories, and this one was pretty well-told.
The Enterprise is seemingly able to declare its own red alerts - not much fun in that.
My biggest complaint is this show's continued abuse of the transporter buffer - it should not be easy to use it as a form of stasis!
