This was an excellent series, with excellent writing, voice-acting, production, editing, etc.
As of this review, the show has three complete series, and I really hope that there is a fourth. The show does an excellent job of intertwining different H.P. Lovecraft stories... not just slapping names together, but really using the stories and combining them together. It also makes excellent use of folklore and real history, and adapts the stories into modern day.
This podcast is a perfect example of respecting existing works while also building upon them to create something new, and is a worthwhile binge for any Lovecraft fan.
