“Billy Lynn’s Longtime Halftime Walk” (*1/2 out of four) was a misfired war melodrama about a 19-year old Iraq war veteran (Joe Alwyn) who returns home for a victory tour and a halftime appearance at the Super Bowl. Film jumps back-and-forth between the present and his flashbacks to the war but since both sections are dry and tedious it hardly makes a difference. Director Ang Lee received accolades for being the first film to use large-scale 150 MM film format but you’d be hard-pressed to tell even a shred of difference from regular film. A well-meaning but complete bore. Alwyn’s fine performance is wasted.
