Antibodies (2005)

This German policier directed by Christian Alvert is probably a good half an hour too long but otherwise effectively presented.  It concerns the capture of a serial killer who has perversely slaughtered young boys and his fixation with a country cop who has been trying to solve the mystery of the death of a young girl in his parish.  This crime does not fit the killer's pattern, yet is it clear that there is some connection.  What this is and how another tragedy is only closely averted form the nub of the tale.  I can see an American re-make a la "Insomnia" before I can see this movie getting a UK release, not that I think a US-version would be any more acceptable, except to those who avoid subtitles.
