Sci-Fi This Week: Revolution Puts Monroe On Trial, Once Tells A Mermaid’s Tale

We’re almost into November, which means two things for television: first, the stops are about to be pulled out for November sweeps, when the ratings are all the more important for networks and so the stories, guest stars, and shocking plot twists tend to get bigger.

Second … well, before we get to the excitement of sweeps there’s a holiday this week, so several shows will take the week off.

Here’s your day-by-day schedule for this week in science fiction and fantasy television:
