Series started off alright and intriguing however it became overly grotesque and many complex shifts in timeline that it's hard to follow. Just the first episode already has issues like a kid going to the crime scene and being the weird chain of custody for police custody.
There are too many over the top monologues with exposition, this made it feel fairly dull to watch. I really wanted to like this series, as it was intriguing but when you have too many flashbacks, much too long and contains many weird character decisions that it's hard for audience to care. It would have been nice if it were 4-5 episodes shorter, get rid of some filler scenes that doesn't serve moving the story along and too much talking.
Overall 6/10. Signal is a much better mystery drama in comparison.
