Adjust your expectations
My not-very-sensitive kid loved it - I was more scared than she was. There was plenty of terror and violence but actually less outright gore than I expected. The more mature content consisted of a few suggestive comments by a main character, a bit of tame kissing, and fair amount of swearing (more than in Jurassic Park, no F-bombs though).
As a fan of the original Jurassic Park, which still holds up incredibly well more than 20 years later, I had to quickly downgrade any expectations I had for plot, acting, direction, and cinematography. The script is forced and clunky, and there is no Jeff Goldblum around this time to deliver the weightier lines. Filling out the plot are a few weak and kind of silly subthreads (uptight woman in a business suit falls for rough-around-the-edges raptor tamer! Dark military-industrial complex types want to weaponize velociraptors!). Let's face it, though, the central question of Jurassic World is "what could happen if vicious dinosaurs were let loose on a mass of theme park attendees?" The dialogue really isn't necessary. Think of this as a B-movie - a Godzilla-type blockbuster with a few horror elements mixed in - and enjoy what you can while the kids gawk at dinosaurs eating people and one another.
