While watching the movie, I was thinking the unassuming and uneventful details seemingly resembled to the realities of a possible life story. Out of my own curiosity, I did some diggings online and found out it indeed was a true story. If it would have been fictional, more dramas would be added to entice audiences. I would think.
However, following the history of the story without changing the period would be my preference. Because the subject is hard to be glorified into a undying romance like Romeo and Julia no matter under any circumstances. Incest happened most likely under some unusual circumstances. This one happened to be in an abusive marriage which might win over audiences' empathy and understanding instead of appalling which would be most likely response. The ridiculous scene with the helicopter should be cut. It was confusing with modern and 17 century surrounding interchanged. It might be a better idea just following the events historically and presenting this human tragedy truthfully to audiences .
Real story should be told as it is to respect its facts.
