Tonal inconsistencies, an inferior reshot ending and behind the scenes protagonist drama aside, I found the film enjoyable the first time I watched it in cinemas. Curiously, over the time it has really grown on me, becoming my favourite live-action superhero film after Burton's Batman films, Batman Forever and Watchmen. It might be in large part due to seeing Micheal Keaton back as Batman, Benjamin Walfisch's truly incredible score and the Batwing action. But it would be silly not to give Ezra Miller props for his acting chops. He delivered the emotional parts really well, and playing three versions of a character, opposite of himself, is no small feat.
It's a shame the film didn't make more at the box office. Most other superhero films are far less nuanced or entertaining that this was.
