The TVI Take

Richard Ayoade's 2010 directorial debut, adapted from Joe Dunthorne's novel, set in Swansea. Craig Roberts plays a precocious fifteen-year-old whose self-aware narration is the film's structural joke and emotional limit.

Ayoade's debt to Truffaut and Anderson is explicit but the Welsh-specific texture is original.
