I marathoned all of them that were available at the time 2 years ago.
Here is my post from the 31 Days of Horror thread from Sept 28, 2020. I bolded the part I remembered the most. I think that documentary was pretty awesome TBH.
"Last week I did an Amityville movie watch. Geez there are a lot of them. I could write a few paragraphs on each one, but that is always my hang up when doing the format of this thread... I watch so many movies that it would take me hours to write up my feelings on each one.

I watched all those and honestly, the documentaries were easily the best movies, particularly the one called My Amityville Horror (2012). This movie is an interview with Daniel Lutz, the boy from the book who was only 10yrs old during the 28 day ordeal in the Amityville home. He is an honest, real, and convincing historian. He is also a fucking asshole with a chip on his shoulder who acts like he could explode in a violent rage at any given moment. The movie was fascinating. I couldn't take my eyes of of it. Daniel is very obviously a traumatized and emotionally unstable man. His accounts of things are hair raising and 100% true, at least to him. There is a point when the documentary goes off the fucking rails when they visit the home of Lorraine Warren. You would know her as one half of the famous paranormal investigator team of Ed and Lorraine Warren. They have been played on screen by Patrick Wilson and Vera Farminga in movies like The Conjuring, Annabelle, Nun (were they in Nun?). Anyway, Daniel very obviously has an immense amount of respect for this women: almost a reverence. At one point she breaks out a piece of the true cross (lol) and Daniel kisses it and I think people started crying? It was fucking weird as shit though. It is obvious that Ed & Lorraine (and Daniel too) were hardcore catholics. Like, crazy catholics. The movie shed more light to me, sometimes unintentional, than the book or all the above movies ever have. It was a great documentary and I highly suggest it."
