Josiah Morgan’s review published on Letterboxd:
This is a superhero movie about companies acting as private contractors to steal freedom from the peoples (primarily Eastern & African in ethnicity i.e. the entire central trial conflict) whilst the rebels are portrayed as freedom fighters ("good guys") whilst simultaneously portrayed as non-people who act callously, as callously or even more so than the capitalists they pertain to be against... even when all is said and done, Bruce Wayne/Batman is the head of a commercialist empire and Clark Kent works for a dying industry notorious in its manipulation of truths to portray its own biases. Every action is derivative of another action.
Even if you aren't a fan of the politicism, there's the pure bombast of Snyder's filmmaking, the constant evolution of overhead images to portray moments in which there is a lack of any distinct 'God' or 'being' in control, the steady cutaway images developing the thread of father and son (actor and reactor): Wayne is Batman due to the death of his parents, Luthor is the man he is because his father was absent, whilst he functions as a father figure for Doomsday... conversely, Irons' Arthur steps in as a mentor perhaps equally as alcoholic and ruined as Affleck's Batman (there are hints that this character goes far further than we've ever seen before and Irons' performance displays this in full force). Everyone's a son of a someone.
There are even people who enjoy and appreciate and understand and recognize all of these things yet feel the film loses itself as it hurtles toward its final third-act series of explosions and punches but the key point of difference between this and other blockbuster fantasies is that the violence here is not designed to expend and confront the audiences with a pleasurable way of releasing tension, but to build - every shot fired/punch that connects/moment is a further piece in a puzzle that isn't entirely elucidated until the climactic death sequence, a rivalry that ultimately finds itself irrelevant as two men find consolation in the similarities between their parents. Once more: everyone's a son of someone.
The true irony in the title of course isn't that Batman and Superman are not as diametrically opposed as we are led to believe, it's that 'Justice' (whatever that means) has never, and can never, exist in this world, where everything is out of balance, where everyone's a slave to governance (even the governors themselves), where angels and demons, gods and humans, politicians and civilians live side-by-side.
