You can't say that the film Shazam! Fury of the gods is bad, but it is not a masterpiece either.
The film is made for the younger audience. You shouldn't watch it if you expect something like "The Dark Knight" or "Man of Steel" but you should watch it if you liked the first part because the second one is even better and funnier.
In some parts it was silly and pointless but it should be clear that this is a family film and they don't always have to make sense.
In summary, it's a good film that you don't have to watch but if you have time and want to watch something new then it's a perfect choice.
