If you loved By the Sea, try In the Land of Blood and Honey
A bridge between a film you've already seen and one most people haven't. In the Land of Blood and Honey has roughly 4.0× fewer votes than By the Sea — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Angelina Jolie, and they both carry the slow burn mood tag, and they sit in Drama / Romance territory. If that's the register that drew you to By the Sea, the second film will land in a comparable space — through a different lens.
What In the Land of Blood and Honey is
A former couple reunites under very different circumstances in a war zone. Danijel, now a Serb soldier, commands the camp where Ajla, his ex, is imprisoned. Their past romance complicates the present—all while bullets keep flying.
