It's good movie not great but good in general I say a 7/10 in general...
Although for a live action DC movie I give it a 10/10 because DC has been awful with their live action movies... besides the "batman movies.. .."
People giving this bad reviews seem to be missing some key points... I won't mention most of them because of spoilers just the really obvious ones...
Black Adam started off as a villain but eventually becomes a anti-hero in the comics.. So there nothing wrong with the movie treating him the same.. People saying they changed his character for the movie are wrong....
The boy in the movie is annoying yes but he's supposed to symbolize something about his past ... ( I won't say what because of spoilers but it's fairly obvious if you seen the movie...) So he is needed in the movie....
Again it's not the greatest movie in the world but it's a solid watch with great movie effects and lots of action....The 2hrs just flew by because there is no drag in the story ... and having an Anti-hero protagonist is always fun..
