It’s sort of weird being honored for the worst day of your life. A young Iraq war combat veteran (Joe Alwyn) and his Bravo Squad comrades are honoured at halftime during a football game home in Texas approaching Thanksgiving in 2004 . Parallel flashbacks (to the incident being honoured; to a previous homecoming?!) are intercut with the game. The high point of the event is a song performed by Destiny’s Child (in reality some stand-ins shot over the shoulder) and this is intercut with the assault in Iraq in which Billy rescues his hurt commanding officer, the mystically minded Shroom (Vin Diesel). His dad’s in a wheelchair, Mom doesn’t want politics discussed at dinner, his sister (Kristen Stewart) is the reason he volunteered after he injured her boyfriend following a car crash that left her with a scarred face. She wants him to get an honorable discharge because she feels guilty. A film so lacking in dramatic impetus as to be almost entirely inert with a lousy structure that drains the very lifeblood from the narrative. There’s some old faff about the soldiers’ story being put onscreen and the deal is welshed on by team owner Steve Martin who is clearly having a laugh in a straight role. Garrett Hedlund, as the head of the squad, is the only actor to attempt anything resembling a performance. Adapted by Jean-Christophe Castelli from a book by Ben Fountain and shot at pointlessly high speeds by director Ang Lee who probably did it that way to stay awake. Mystifying to the point you’ll feel like you have PTSD afterwards.
