Honor Thy Mother is based on the Jerry Bledsoe book "Blood Games". The acting is superb, the story line better than fair. The book, however, is excellent. Sharon Glass, is fantastic as Bonnie Von Stein.
I would have been much happier had they stuck to the actual book for their facts and did not exaggerate on the D&D aspect.
I would recommend this movie over the Blythe Danner/Gwenyth Paltrow "Cruel Doubt". I'd also recommend "Blood Games" over Joe McGinniss' book "Cruel Doubt".
For more information on this case, there is a wealth of information on the web, and articles on the Herald-Sun (Charlotte, NC).
