The Exorcist Tapes is the third movie in the very loose Paranormal Entity/Investigations franchise and is made by infamous production company The Asylum (Who I'm sure I don't need to introduce).
It tells the true story of Anneliese Michel and the case of her supposed exorcism and the two warring factions who tried to decide her fate. The doctors who wanted her to go to a hospital and seek medical treatment and the parents/priests who deemed her possessed and demanded she be subject to an exorcism.
The movie plays out as if it's real footage of the event which I find a tad exploitative and in bad taste considering the true story, what happened and the fate that Anneliese was finally dealt.
In true Paranormal Entity and Asylum tradition the movie looks ugly, has no budget behind it, has a mediocre cast and people behind the camera who must have just graduated amateur film school.
If you want to know the story of Ms.Michel then google it, maybe watch the documentary but leave this nonsense in the cold where it belongs.
The Good:
Nope
The Bad:
Rather bad taste pretending it's real footage based on what actually happened
Everything is just so poor
