I enjoyed this series, but as mentioned by other reviewers, it really would have been better if it had been presented as one 2 hour movie, or even divided into 2 or 3 episodes. Chopping it up into 14 minute episodes made the film story drag much slower than it would have otherwise. That said, my review of the film itself is positive.
The story's ghost was presented in a different way than usually seen in this type of film, and I much preferred this straightforward conversation over the overly strained mystery usually delved into; the mystery of her death and who killed her and why was enough of a mystery without adding to it. It was also perfectly logical that the ghost would seek out a professional detective who was able to see her over an untrained outsider (as so many do)--it helped avoid the whole "I can't believe it" trope, or the old "you're crazy!" stereotype. THe detective may be crazy (and that question is never fully addressed, wink wink), but he's good at what he does. and this actually helps the story not only move forward but keep it fresh.
The acting was decent, though if I remember correctly some of the minor characters were less consistently committed. Facts were presented as the detective learned them, with nothing set forward to deliberately fool or confuse the audience (I like that in a mystery) yet there was indeed a mystery. The solution when exposed makes perfect sense in retrospect. Overall, while not an Oscar winner, it was worth watching--though as I said previously, it would have been better as one full movie or a mini-series rather than such short episodes. I don't know if this was initially a web series, but from the description it appears that they plan on additional seasons. Given this season dates from 2017 there may very well be more to come. I for one look forward to it, but I do hope they read these reviews and take them to heart.
