The movie was groundbreaking, and its ideas had great potential for further development. Usually, sequels are made to continue the story on the big screen. Creating this excellent series was a much better decision than producing lousy sequels for the masses.
Fans of the movie get to further explore all the ideas: The Stargate system, used by humans to travel the galaxy for thousands of years; Egyptian, Norse, and alien mythology; true science fiction - with fictional devices and concepts based on current science; and human exploration of our known universe part of what made Star Trek so popular.
You see the characters develop over time, the quirky unexpected humor, the use of an alien who doesn't fully understand American English (like Data), the struggle of the oppressed, the lengths humans go in order to survive, politics and government bureaucracy, and the underlying tenet that there is more to human life then our brief appearance on planet Earth.
