Ben Affleck’s Batman is arguably the most divisive cinematic take on the character, yet there are several DCEU Snyderverse moments that prove Affleck’s Batman nailed several aspects of the hero. The first live-action Batman iteration since Christopher Nolan’s Dark Knight trilogy, Affleck’s Batman had the difficult mission of replacing a widely praised Batman now as part of a shared universe. Though the idea was for Affleck to be the DCEU’s Batman for years, which would have included a solo Batman movie written and directed by Affleck, the DCEU's Batman's run was limited to two movies, a cameo in Suicide Squad, and what seems to be a sendoff in The Flash.
