Normally I give network shows a hard pass. But this one actually surprised me in the things it did. The scares are pretty good. The chemistry between the three is really good as well. Out of the three, two are hard skeptics. Mike Colter's character is a true believer, but is willing to give benefit of the doubt to the skeptics.
The story revolves around a group that investigates paranormal behavior, and assesses psychological dimension as well as spiritual dimension. There is usually not a clear cut answer to the questions. The show sometimes falters into network tv tropes, ie technology scenes like hacking, AR/VR, talking about online communities, etc are not really good. There was one scene where supposedly the mystery has not been solved for 500 years but...the protag solves it in few mins? But stuff like that is very few and far between an otherwise a smart show.
I'd give the show a recommend if you are in the mood for a show about Paranormal Investigations Unit. Oh and also Michael Emerson is in the show and he is delightfully evil.
