“Stalker” (** out of four) was a lurid pulp melodrama about a young man (Vincent Van Horn) who has just gotten to first-base with a new woman (Christine Ko) that he met when he meets and befriends an unstable Uber driver (Michael Lee Joplin) who turns out to be a nutcase who is intent on taking over and destroying his life. Good acting and filmmaking hold your attention for a little while but after a while you’ll be numbed by the unpleasantness and violence. Final plot twist is arbitrary and unnecessary. Perhaps it’s time that filmmakers give the psycho Uber-and-taxi drivers stories a rest for a little while.
