This season continues to be a bit of a slow burn, and I'm not sure that's going to work out very well for the show or the audience unless things start to pick up the pace. I like the premise, and it's clear that they are building up a status quo that could eventually turn very dark on a dime, but this focus on the "curse of the week" is turning into a curse of its own.
The spectre of "The Troubles" is still hanging over everyone's head as each new case unfolds, but unlike the second episode, where it seemed to be taking a more prominent place in the story, it's mere window dressing here. The focus was on fleshing out the character of Duke, but even that didn't seem to be in the spotlight enough. And given that Duke's character traits are clearly going to be an important part of the cast chemistry, they needed to drive home his Han Solo-esque nature.
The central mystery was nice enough, despite how disgusting the rotten food angle was. (Seriously, the exploding cow stomach was a bit much!) But here is where I have an issue with the structure of the show. All of the consequences of the fallout at Second Chances were explored from the perspective of the main and guest characters, even though it was supposed to have affected dozens around the town.
In other words, unlike "Butterfly", where Reverend Driscoll and his bigotry was reflective of a segment of the community at large, there was no voice for the community itself in this episode. In fact, there are no strong recurring characters that serve as the connective tissue to the general population. Instead, we are left to assume that the masses are represented by the family members and friends that bear the brunt of the sudden emergence of these "curses". And that's not really enough to carry the show.
What the show needs to do is build a quirky supporting cast that can serve as the expository voice for the community, providing the necessary insight into how these recent events are changing the sentiment of the town as a whole. In other words, it's all about placing these bizarre cases in the context of what it means to Haven. Without that touchstone and perspective, these events happen in relative isolation, and the audience is left wondering why they are supposed to care.
