Misbegotten

You see there's this sociopath (isn't there always) who donates his sperm to this couple who're having trouble having a baby. He does this so he can become a daddy (like, since he's already killed a bunch of people, normal sex - or even rape - is way out of the question, right). Then he stalks the soon to be Mommy so he can eventually rock the baby's cradle and take family home movies.

Makes sense, right?

Although this plot was really awful, the movie had one redeeming quality: Dillon's portrayal of the stalker. In the beginning he was charming and completely likable as the true sociopath must surely be in order to gain the trust of his eventual victims. His performance made the whole mess just barely watchable.
