Saw it when it was released on video tape as well. Had very fond memories of it, and those didn't disappear even when I saw it again years later. I guess it's because of the setting, the DJ's job, the point that I saw it with other horror flicks from the late '70s, etc.
I saw it new in the theater and thought it didn't make sense then. If one were to go back to page one of this old thread I started, my review of this wonderful and DUMB movie is at the start.
