### Sominex

Included in the interviews with Carl Glatzel is the concern that their mother had been drugging them with Sominex on a regular basis, by putting it into their evening meals. Newsweek asked the medical director of UCI Health Sleep Medicine Services about the possibility that Sominex could be an explanation for the alleged possession, only to be told that medicines containing diphenhydramine hydrochloride are only meant for short term use, and that there are no studies on potential long-term effects.

## Release

The Devil on Trial was released on Netflix on October 17, 2023.

## Reception

The New York Times stated the content was superficial and inconclusive, with the material having been 'mined' for "lurid titillation". The Daily Beast commented that the recordings of David Glatzel's alleged possession, obtained via microphones placed by the Warrens at the time, sounded "like a young kid straining to say wildly profane things." A Good Movie to Watch stated that Netflix "should try harder".
The Decider suggested viewers "skip it", stating that the film spends a lot of time indicating that there may be some basis to the claim of possession before focusing on the eldest of the Glatzel siblings, Carl, who believed otherwise. Common Sense Media asserted that the film would engender debates on "the world of the unknown".
The GATE mentions that the film left them feeling empty and expressed disappointment that Carl Glatzel's statements weren't more thoroughly incorporated in the presentation of the case, describing the film as "basic" and saying that it didn't capture their attention.
The Diamondback review is very positive, stating that the presentation left them conflicted as to whether the possession happened, but that it was very entertaining. The Daily Campus shares the sentiment, giving the documentary a 4.5 out of 5.
Screen Rant points out that the documentary presents the Warrens as legitimate, which they say detracts from the documentary's impact. They also point out that The Devil on Trial is far from the first documentary on the subject. /Film counters this, acknowledging that the Warrens are not given the same positive press that they receive in The Conjuring franchise, while acknowledging that there is concern over the presentation of the possession in the audio tapes.
