Most of the epsiodes I've heard of this series are pretty bad. Arch Oebler can lay claim to being the Ed Wood of classic radio.
I'll admit to having a love-hate relationship with this show. The bad episodes could be really bad, but there were some good ones. Battle of the Magicians was pretty decent. Some (like Poltergeist and Little Old Lady) were fairly good stories but got ruined by atrocious acting.
