Episode 1

The first episode of the series is very slow, which is the primary reason why it is rated so low. It's 1977 and an FBI agent, Holden Ford, is called to deescalate a precarious situation involving a hostage.

It's a tense scene to start the show but after that, the thrills die down quite quickly. Bill Tench is introduced to be the partner of Holden as both of them drive to Iowa to have a teaching class. Fair to say, their students weren't of much interest.
