My five TV series selected on being Canadian or American and being relatively unknown.
Poltergeist: The Legacy (1996 to 1999)
Beauty and the Beast (1987 to 1990) (crime fantasy, no connection with the Disney films)
Warehouse 13 (2009 to 2014) and Eureka (2006 to 2012) - separate series but connected
Haven (2010 to 2015)
and the best of all and the obscurest - Key West, only the one series of 13 episodes from 1993. It was shown in the middle of the night here, isn't available on DVD. Fisher Steven and Jennifer Tilly.
