« its characters address the gauche subject of the eternal, naturally, through the Judeo-Christian lingua franca instead of via a vague, enervated "spirituality." »
That is the only line in your review I can agree with. Of course speaking of "eternal" is gauche, since there is no such thing as eternal life. Nothing in this film is original, it has all been done before. I can watch swirling liquids and gases, and I have plenty in my many years as a cinephile, but to have an entire Christian allegory based on metaphysical aspirations to actual physics is dishonest and manipulative.
