Two and one-half stars. Unrated. 104 minutes. The sometimes impenetrable Yorkshire accents in the English drama “God’s Own Country” are still less thick than its central character, Johnny Saxby. Played by the young actor Josh O’Connor of the British TV series “The Durrells of Corfu,” Johnny is something of a blockhead: a gay 20-something who, when he meets — and falls for — the Romanian dreamboat (Alec Secareanu) who has taken a temporary job on his father’s sheep farm, proceeds to do everything possible to wreck the relationship. Secareanu’s Gheorge would be a catch even if he didn’t look like a rock star in feces-stained coveralls.
