I can't speak to the accuracy of the full portrayal of the Amish, although it is clear that this represents one of the stricter Amish sects, and they are right about some aspects (i.e. no reflectors on buggies). I thought it was a good story that held my interest. It has some similarities to Witness (not just Kelly McGillis!) in terms of the outsider in their midst. There's good tension in multiple story lines, and a crime to solve as well.
