HELP I didn't understand it (spoilers)

Tbh this film was such a huge miasma of overt symbolism, and as you said Lisaplus1 it also seemed laboured and meandering. The 'basic plot' therefore kinda gets lost in the flood of iconography and repetition. I must also be a bozo who shouldn't watch films like this, as there was a lot of the 'basic' plot that I also didn't quite 'grasp' because I was looking for something deeper in it.

So revenge, forgiveness, dark, light, damnation, redemption - I get all that, but that seemed a bit crass and obvious really. The Last Seven? Not just the last seven people left surely? I was thinking along the lines of the last seven utterances of Christ he (allegedly) made during his last hours on the cross. Seven is said to be the number of perfection, the number of God. One of the things Christ said was summat along the lines of 'Father, Father, why hast thou forsaken me?', is this a reference to the idea of a father failing to protect or abandoning his child also heavily implied in this film?
The reporter William Blake, is this significant as far as the meaning of this film is concerned. On his death bed Blake was still working on illustrations he was commisioned to do for Dante's 'Inferno', which ofc is about descending into Hell and returning. Odysseus also did this in 'The Odyssey' (visited Hades and returned) and much of Blakes illustrative work reflects an interest in the ancient Greek pantheon.

So overall I'm not convinced that the whole film is pulled together at the end. I'm not even sure whether it's a good film and I just missed the point of it, or it's a film that tries to be more than it actually manages to achieve. Maybe the 'basic plot' is all that there is to it, in which case it's a very disappointing film. I don't think that not understanding the film deserves ridicule because I suspect that the director and cast themselves would be hard pushed to provide any kind of satisfying interpretation.

Yeah why does William have to remain in limbo?
