I feel the need to make some comment on the movie as well to relativize all the negative critics a little (and I hereby apologize for grammar mistakes as I am not English ;-). I was somehow shocked when I realized how the movie is promoted in the UK and as well here in Germany - the title of it has changed from the original "Older than America", and so has the original cover. And the promotion text is so stupid and totally misleading I can only shake my head. I can understand that someone who wants to watch a good horror movie is disappointed by this. Also people expecting Bradley Cooper to be the lead role - the lead role definitely is Georgina Lightning and maybe Adam Beach...
The film is NOT, I repeat NOT a horror movie. I don't think the intention of the writer/director was to make a horror movie. It is more of a story on how the Indian children were mistreated in the Native American boarding schools and the effect it had/has until today. Some parts are indeed a little bit "spooky", but in Native American live spirituality and visions play a big role and visions are considered as "real". It is not a perfect movie, but I found it very good and emotional, thinking that the subject on that boarding schools is real - it has happened and it has not happened that long ago, and this could indeed be called horror.
For more reviews you should check under the original movie title "Older than America"!!!!
It is a shame of amazon and/or the Europe promoters of the movie to mislead the viewers through wrong promotion texts and covers!
