While I find this show interesting on levels, I also find it concerning.
Provoking evil to harm proves what exactly?
Why aren't they doing their best to move these entities on, without provoking violence from them? I can only surmise it's for TV, which is pretty rubbish & provides others with the idea this is a good thing to do.
There is also binding of 'evil entities' etc to items eg a chair/table/ book.. any inanimate object
There is no Medium present to confirm if the 'entity' is actually a demon, or a violent human soul that hasn't moved on.
Binding souls to objects instead of moving them on, creates further harm.
Take these objects they have in the storage to a reputable medium to find out who/what is going on, and safely move the entity on, if possible.
How would they like it if they were trapped in a doll unable to move to the next plane?
It's not good enough. There's far too much antagonism, and nowhere near enough depth of expertise, speciality etc to handle these situations.
It's like kids stirring up a hornets nest.
If this isn't what they intend, then there needs to be a reputable Medium present to properly instruct them what is going on and how to do resolve it.
That's my 2 cents.
So many 'ghost Hunter' type shows where no one is actually trying to help these souls being exploited in their death, for rubbish TV.
Leave them alone unless you're going to actually help them.
Yes, I like the show The Dead Files. I find their practice to be more respectful.
