The Catalyst is not a literal deus ex machina. A deus ex machina is a plot element or device that comes from nowhere to save the day; the Catalyst does anything but save the day.

Incidentally, does anyone know if the leaked script is still available somewhere? It would be interesting to compare it to what we actually got.
