Bruce Wayne enlist the support of a new ally Diana Prince to fight more dangerous enemy ever after he was inspired by Superman's self-sacrificing act which restored his faith in humanity. They manage to unite the metahumans into a team together with Batman and Wonder Woman as fast as possible. It may be too late to save the Earth from catastrophic proportions damage, even though the league of heroes includes Batman, Aquaman, Cyborg, The Flash and Wonder Woman.
There's some welcome levity, some genuine conversation (as when Bats and Diana share a drink), and a few moments that feel like really good comic book panels (especially mid-credits). For some, that may be enough.
Gal Gadot's Wonder Woman got the tone right last time, which suggested things were looking up. But without director Patty Jenkins around, she's subject to the dismissive male gaze for which Hollywood's long been criticized.
