How we stay independent. Editorial scores are not for sale. TVI may take on paid advisory or research work, but no commercial relationship buys coverage, advance access to scores, favorable treatment, or a change to a published finding. We pay for our own streaming subscriptions, and no reviewer sees sponsor data or affiliate revenue tied to a score. More about how we work →

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.
