THE FOLLOWING
Fox, 9:00 p.m. ET
This is the fourth episode – the last one sent to critics in advance – and it’s the one that will either impress its fans or test the loyalty of viewers. There are suggestions that this series already is borrowing from the “Red John” story line on The Mentalist, as well as from the traumatized-child backstory of Dexter. It’s an interesting amalgam, but also an increasingly unsettling one.
