As a horror series, The Strain has had plenty of tense, disgusting, and squirm-inducing moments. Lots of body horror. Some close calls and near misses. We’ve watched likable characters become infected, die, or transform into the undead.
But for all of the cringing and shock factor scenes, I had yet to be properly frightened. I know I’ve built up quite a tolerance for horror but I’m not carved of marble—and I go into such series hoping I’ll get a solid case of the creeps at least once or twice.
With “The Third Rail”, I finally got what I was asking for: an episode that reaches, then maintains, a fever pitch of nerves. I’m not ashamed to admit that I had to actually pause it twice and get up for a brisk walk around the house to settle my stomach; I was that tense.
