Love at First Bite(1979)

Dracula and Renefield relocate to '70s era New York in search of Cindy Sondheim, the reincarnation of Dracula's one true love, Mina Harker. "Trouble adjusting" is a wild understatement for the Count as he battles Cindy's psychiatrist, Jeffrey Rosenberg, a descendant of Van Helsing, who may almost certainly, possibly, may be in love with Cindy too.
