Another point in the Goa'uld's column is the gradual build of them as threats. At the beginning of the early seasons, Earth was only barely on their radar, and the characters tried to keep a low profile, but things escalated and they developed allies. At the beginning of season 9 the Ori show up and are comparatively static threats for the next 2 seasons and a movie.
