But people actually wanted to see Venom, not even kids want to see this Sonic movie because they know what the character should be and the movie is not that.
In, Detective Pikachu will have to be really bad for Marvel to keep its grip over the audience in week three. Pokemon is a new thing for the movie going public.
Mary is already going to college in Shazam, the other kids are still pretty young. They should try to avoid having a significant time gap in the sequel.
Finally saw Shazam for myself and I gotta say, it was pretty good and definitely my favorite movie in the DCEU.
I hope it's successful enough to warrant a sequel, the Shazam family isn't getting any younger.
