Is this film religious allegory?
First--I love this movie, and I think it works very well as a straightforward sci-fi/horror film. Still, I think there's more at work here...
As soon as I finished watching the film for the first time, I felt strongly that the film was allegorical; specifically, a metaphor for the spectrum of religious fervor. Cappa is the Atheist, Pinbacker is the Zealot, and Searle is in the middle. The Sun stands in for God. Upon repeat viewings, I still hold this interpretation.
In listening to the DVD commentary, it seems that the writer and director disagreed on this question. As a viewer, what do you think?
