Interesting how the article is not mentioning the (inverted) Christian allegory as if that doesn't even exist. It's not even subtle if you actually watch the film, like that's almost the point of it.

The original book is even more explicit about that, like Theo does a makeshipt baptism on the infant amidst all the fighting.

I was going to say the same thing, there is so much Christian symbolism in the film that to not mention it at all makes me think the author is just not aware of the things the film is referencing.
