Almost all critics are trying to bury this movie because it is right-wing and Christian (all the other left-wing anti-Christian movies were never a problem though).
The movie is a cheap production, all the major plot revolves around two guys chatting in a room, but the dialog is really well written and both actors are doing a great performance.
It is also very different from modern horror movies, it does not contain jumpscares and shaky cameras. It would probably be better classified as a psychological thriller.
Even if you are not religious but have some interest in Christian lore you will probably enjoy it.
At your recommendation I just watched it, and it was indeed enjoyable. Great, great performance by the prisoner on death row. Some slightly cringe Atheist vs. Christian type of dialogue, but it was more than made up for by the actors.
