Horror movies in the 1980s were defined by technical format more than style or narrative convention. The video revolution proved a boon for the genre, giving new life to movies that struggled in theaters while providing an entirely new platform for films without the resources for a theatrical release. It also allowed teenagers to see R-rated movies without having to go to the theaters, opening up a new demographic of eager fans. After the gloom and doom of the 1970s, the genre had a chance to kick up its heels and make scary movies fun again.
