Justice League is the most impressive to me, for the fact that it exists at all as Snyder's undiluted vision. I'm not a fan of his generally but with this film I think what he had been attempting to do with the DC universe finally clicked, and the film feels like a larger-than-life epic depicting these mythological gods and goddesses. The 4-hour length, the chapter breaks, the aspect ratio. It just worked for me, more than I thought it would. Unlike BVS its narrative is refreshingly simple and it isn't bogged down with this pretentious nihilism, so it allows for the movie to take its time with the characters and actually create emotionally resonant arcs especially for Cyborg and Flash (even though Ezra Miller is miscast in the role). I'm glad it exists and I'm glad Snyder got to finish and release it as a last grand statement on his DCEU, for as incredibly flawed and mishandled as it was.
Man of Steel is infuriatingly mediocre. BVS is an astonishing failure that tries to do and say so much and fumbles all of it so spectacularly that it's still fascinating to watch and dissect. I do admire Snyder's ambition even if his reach is always exceeding his grasp.
