I've only seen the first 4 episodes of the series but it's still enough to get a good perspective on what the series may go like. When I watch movies or series, I don't just watch for the stories. I see how the actors interact with each other. Sometimes, even with bad actors, you can still get some entertainment from their perceived real emotions.
The story isn't just linear as it appears on screen. If you just follow the story as if you were reading a script, you won't get a 3 Dimensional story as opposed to the substance that the individual actors add to the film. In this series, Kelli Giddish, shows bits and pieces of her character's feelings towards the people she investigates and perhaps, a little bit of her real emotions. It's the same with Bishop. Bishop seems to be the kind of guy who can focus well on a certain task. In the first and second episodes, these two actors didn't seem like strong actors. After I watched the other 2, they seem to grow into their parts and begin to add to it.
This is one of those series where the story may not seem that interesting at times but if you watch their interaction, you can probably make a more interesting story in your head about their relationship to other characters. It's something that I do when the plot line gets boring.
