Shepherd is a quiet focused film on the tragedy and grief of a man (and his dog) who leaves his home taking residence on an isolated island to tend to sheep. He's mourning the death of his wife, but given the reticence of this character, all we know is that she died. The woman who instructs him on his duties, and who will bring supplies, takes on a meancing nature as the lead starts his descent into isolation reacrion. Is it psychosis or supernatural? The film continues with elements increasing in their bizarre nature and displays some surreal visions. At the end, we find one piece of the puzzle from the lead character, helping to have some satisfaction at the end without full clarity given.
Tom Hughes does well in carrying this film as he is largely alone on screen. He portrays the numbness of grief expertly, and he manages a realistic depiction of that descent into Hell or madness without falling into stereotypical behaviors or characterizations. His performance makes the resolution and uncertainty credible for the film's end.
