In the beginning of the movie the main characters collapse the Ben Franklin Bridge. Throughout the rest of the movie (including when the dome is created, and later shrinks), the Ben Franklin bridge is shown as intact.
When Shazam meets with Hespera, the drink cups on the table change position from close together to far apart depending on the shot.
When Darla first encounters the car with the women, there are three (3) kittens in the basket, when she picks up the basket there is only one (1) kitten in the basket.
The cars hitting the dome while at full speed on the bridge should have crashed much more violently.
Billy is said to be turning 18 in soon and will be aging out of the foster care system. In the first film, Billy was stated to be 14 years old. Dialogue here indicates that 2 years have passed since the events of the first film, meaning Billy should be 16 years old, not on the cusp of 18.
