"Harper's Island" TV Show on CBS (2009) --- In this mystery series, a group of friends visits a secluded island off the Washington coast for a wedding...but the fun is cut short by murder. The murderer claims more victims, leaving the dwindling survivors to figure out who's behind the plot. Starring Katie Cassidy and Christopher Gorham. A fun and campy spin on the genre and an enjoyable (if short-lived) summer series.
Not the best acting in the world, but an interesting storyline: when the entire world's population blacks out for approximately 2 minutes, everybody gets glimpse of their lives 6 months into the future.
