This review may contain spoilers. I can handle the truth.
A brilliantly acted (especially by the lead, Paul Kircher, the new 'It' boy of French acting) and deeply moving French film from writer/director Christophe Honoré. Kircher won the San Sebastian Film Festival Leading Actor award for his performance here.
Winter Boy so impressed me I have watched it three times in the 72 hours allowed by Amazon Prime after paying for the rental.
So far, the film has collected a further seven nominations across multiple European film festivals.
