The Shards. Anyone that has seen the full season can tell me if it’s good?

Couple questions as I haven’t started with it yet.

1)- Is it a miniseries? I know the book is about a serial killer. So do the season end with us finding who it is and all that? Because I heard rumors Murphy wanted to elongate it and do multiple seasons.

2)- Is it worth a watch? Does it go off the rails like every other Murphy production?
