I read a bunch of the reviews , they don't seem to have anything against the movie that much they just say it's kind of boring
BUT they ALL knock Will and Jayden saying this was a vanity project he set up for him to star in , so I think it's probably a solid action movie , but people are taking the stars and directors public image and using that against the movie.
A lot of the complaints are that Will basically sits there and talks all movie and Jayden does everything , but they billed it as a Will Smith movie.
EVERY review I read talked about nepotism and how Will basically made the movie for Jayden to star in. Which seems more like a personal attack than an actual in movie critique to me.
