So much is happening every second, and yet it feels like so little gets accomplished. The illusion of forward-momentum. I thiiiink some of it is trying to comment on the state of superheroes in movies now that don't seem to care at all about civilians? So many of them now are only bothered about their own situations and that could be an apt thing to go for with Black Adam, but it basically just boils down to one line and the movie never stops for anything.
If Dwayne Johnson's overblown enthusiasm for the character and his piece of the DC universe wasn't so well known, I would've thought he was sleep-walking through the movie. Black Adam isn't exactly deep or fun to begin with, but I definitely know people who will be disappointed with the lack of The Rock's usual charm and charisma.
Though watching it is a great opportunity for you to think about more productive things, like what you're gonna have for dinner. As long as you're prepared for how exhausting it all is, I don't think there are any other lasting effects to worry about.
