I mean, come on, Devlin and Emmerich came up with this idea with limitless potential, a wormhole allowing instant travel to anywhere in the galaxy, and the best they could come up with was a hackneyed ancient-astronaut story and a replica of ancient Egypt? What a profound failure of imagination. The movie is a tremendous letdown. What impresses me so much about the TV franchise is how they managed to take such a shallow foundation and build such a rich and imaginative universe upon it.
In the TV show we get the alien-astronaut story and replicas of Egypt and some Middle Age villages.
And then you're being completely unfair, comparing a TV show with 10 seasons to a film with 2 hours like that.
