Mister John

off the top of my head, I could see snippets/influences of Claire Denis 'The Intruder', and David Lynch, in addition to the more obvious, such as Antonioni's 'The Passenger', and Bogdanovich's similarly-themed, and Singapore-set, 'Saint Jack'. (and at a stretch, I could probably make some Bergman connection, also).

So I guess you could safely conclude that I would classify it as an 'art-house movie', although, perhaps more kindly, an interesting failure than a cinephile's self-indulgence.

'The Passenger' connection might seem the most obvious, on the face of it, but I thing the Singapore connection is more relevant, and particularly to the degree that the filmmakers sought to make an exotic, even mystical connection with the notion that the waters in which the 'Mister John' of the the title had drowned were attempting to claim his soul; which led to brother Jerry immersing himself in those waters with the aim, presumably, of reclaiming his brothers' soul.

I found more interesting the dreamier images set in the bar/brothel, but the filmmakers seemed too focused on domestic pregnant pauses and stares - mostly featuring Aidan Gillen's Gerry - and trivial or tedious dialogues: not so much 'sound and fury' as sound and boredom, signifying nothing.

But I will watch out for the filmmakers next work: if for no other reason than that they've been influenced by the right people.
