This was supposed to be set in the "Bible Belt" of Northern Ireland. Well, as someone who grew up there,and was a child in the era depicted in the film it just didn't ring true! The accents were all over the place - anything but County Antrim/Derry. The church didn't resemble any I have ever seen. "The Church of God" is a pentecostal denomination but the one in the film was certainly not pentecostal! The elderly minister at the beginning was dressed in the robes of the Church of Ireland (Anglican)- and no C.of I. would call itself "The Church of God". The minister was often addressed as "Reverend" - they may do that in some parts of the world but I never heard it when I lived in that area. Ministers were addressed as "Mr ......"
This film was very badly researched and cast - fairly typical of Irish cinema - annoying! A film can have a great plot, but if it doesn't look authentic, it is rubbish.
