Not the best film but the theme involved "ascension" by name and how an "ascended being" can also be a totally evil goddess/god. Also, how chanting can cast a powerful spell...reminded me of my old cult CUT..we chanted "decrees" to cast spells over reality. Some interesting plot lines.

The movie covers SG-1's attempt to recover the "Ark of Truth", an Ancient device designed to brainwash whoever looks into it. Even though the Ori's promise of Ascension is a lie, the Ancients believed that people should be free to believe it if they wished.
