Of course, Jumanji: Welcome to the Jungle had a lot going for it beyond just The Rock’s star power.
The movie is a reboot/semi-sequel of a beloved and nostalgic property and is riding the strength of positive reviews.
I think this is part counter-programming and part giving audiences something fun and different to see after they have already seen Star Wars.
I would also argue that each of the four leads in this film draws in a different group of people to the theater, and despite releasing in the wake of Star Wars: The Last Jedi, the reboot managed to find an audience.
