There’s a Graham Greene tinge to the story of "Mister John," but – as in "Helen" – Molloy and Lawlor pull back from the thriller-like elements of the plot. They’re more interested in mood and atmosphere, and in tracing the gradual recalibrations in the identity of their protagonist.
Gillen is great... [and] Stephen McKeon's score is spine-tingling too... That the whole should not quite add up to the sum of its parts is no great tragedy; there is enough magic in these meanderings to carry us over the flaws.
Mister John is a step forward [for directors Molloy and Lawlor], chiefly because of Gillen, who thinks his way into this role so surely he levers the whole film open for us... Gillen is perfect at capturing the sense of a man’s lost compass and jittery emotional state in a foreign land.
With Mister John, Lawlor and Molloy have somehow managed to transform [a] combustible blueprint into something that’s hauntingly, tragically realistic and bizarrely funny to boot... [Aiden Gillen's] work [here] is far and away his strongest to date, an inverted powerhouse of brooding tough guy bravado.
Lawlor and Molloy's measured, precise style means their film is always watchable, but in some ways this goes over well-worn territory, and the visual poetry is not always matched by convincing drama.
Elusive, nuanced and poignant... [Mister John] fathoms the depths of masculine identity in crisis, with an emotionally resonant tale given additional flavour by its exotic locale.
Rather than use shock tactics, the filmmakers confidently allow the drama to play out through the performances. It’s a real character piece, focusing heavily on Gerry’s state of mind – pulled off beautifully by Aidan Gillen.
An exotic fantasy punctuated with surreal dark humour... [Mister John] is a complex experiment on evolving identity and the need to escape a damaged life.
Mister John layers technological, spiritual, imperial and post-colonial conflicts to create something that's jarring, discomfiting, but it's a creeping creepiness, a glacial alienation.
