I've only seen the Devil Made Me Do It episode on HBO, so my rating is for that. I love Ed and Lorrains tales of their encounters. Well those of that have been made into films. I never got to see them speak but a tiny hand full of times. I would have loved to see them like the terrible ghost hunting shows we have now in days. Mainly because the little I have seen of them they never used gimmicks, terrible narratives voices, nor seemed to speak in a way they had no clue what they were doing (as shows now in days do).
This show did a good job. Nothing seemed too far fetched or overall dreadful. The minor gimmick used could have not been used. If you do a good job describing/telling your story gimmicks aren't needed.
