From is a show that beautifully stitches together suspense and mystery. Unfortunately it doesn't get to the broad mainstream yet. But since it took it's next step in popularity, there is a lot of hate from a few people popping up on Reddit. Not criticism, but undirected hate almost against everything in the show. After that you suddenly saw ratings on IMDb decline for some episodes, which don't do the show justice.
In my opinion some episodes are weaker in terms of action, because they are putting more focus on the character development. This isn't one of them. From my point of view it has a great balance between keep-you-on-the-edge horror and much-needed dialogue. I, for one, want to care about the characters, and I don't mind a slow burn. It follows tightly the story of the former episode and increases the stress level in the show.
And again, some outstanding acting in it, like from Harold Perrineau and Elizabeth Saunders. Absolute recommendation. Especially, if you liked Lost, The Leftovers and the first season of Wayward Pines.
