Quite a bit different than the grimdark world that is the DCCU. It definitely takes place in the world of the Justice League though, it’s got quite a few references thrown in.
The basic plot and concept is a lot more fun and Shazam (Captain Marvel, no, the other one) is a nice departure from your usual super hero. The villain is kind of neat but feels a little one dimensionally evil. There are a lot of nice underlying themes about what it means to be a family.
It’s definitely one of the better DCCU films.
