“Foe” (** out of four) was a rambling melodrama about a couple (Saiorse Ronan and Paul Mescal) who live in quiet isolation from the rest of society on a secluded farm; when a stranger (Aaron Pierre) shows up with an indecent proposal, their isolated existence and lives are thrown into disarray and turmoil. Beautifully shot by Matyas Erdely on stunning locations in Australia but film moves in fits-and-starts and never becomes fully engaging. Based on Ian Reid’s novel of the same name.
