Mischa Barton in Cyberstalker.

“Everybody’s got a stalker,” Alexis Rose asserts in the expanded lyrics of a “A Little Bit Alexis,” and given my own misadventures in being trailed online, I can’t entirely disagree. In Lifetime’s amusing Cyberstalker (2012), it’s Mischa Barton’s Aiden Ashley who captures the depraved attentions of an obsessive, but the Internet’s merely a gimmick. He tracks the teenager offline as well, eventually breaking into her house and murdering her parents, though the editing was such that I’m uncertain of his methods.

It’s the first of several strangely bloodless acts of violence he’ll commit in the course of the movie, with weapons including a motorcycle, a hacked traffic light and a taser. Why he does any of it, I haven’t the foggiest. How he came to fixate on Aiden, I couldn’t tell you. The screenplay, credited to Kraig X. Wenman, seems to have been composed by an online story generator that randomly inserts words like “IP address,” “algorithm,” “hard drive” and “server” into dialogue that almost never advances the plot.
