Each character is an expert in their respective field, and they all happen to find themselves independently hired to solve the same case. They bicker and squabble yet there is an undeniable camaraderie they begin to develop, and the fact that all of them are sort of dysfunctional in their own way makes me all the more fond of them. They form a little cohort of ghost hunters capable of rivaling scooby doo, and their exploits bring them face to face with forces capable of unimaginable violence and cruelty, be they spirits from beyond the grave or the demons that lurk within the hearts of men. It almost reminds me of playing phasmaphobia with a bunch of friends.
The show is well paced and to the point, with 8 or 9 "cases" usually taking more than a single episode to solve. Yet despite this, there is time made to give the characters personality and also weave in clues to solve whatever mystery they are currently investigating. If you're the type that enjoys trying to solve a mystery before the detective character explains it, it is definitely possible with several of these cases. But that's not to say they are poorly written, rather, the author rewards the clever reader, and though your theories may not always be on the mark, there's a certain satisfaction that can be gained from being given the chance to try.
At the end of the day I would describe this as a comfort anime. That it took me a decade of anime-watching to even stumble onto its name shows how popular it is. I think giving it an 8 is perhaps a bit generous, but when I look back to the past two days where I completely binged straight through it, the only real complaint I have after it is all said and done is that it doesn't have more episodes.
