There is quite a jumpy bit when Ellie gets attacked by the velociraptors. It is only scary the first time you see it, as it is unexpected.
There are lot of suspenseful and intense sense with gore and some comic violence to make up for it.
The film's Oscar winning sound design is famously intense. A great deal of frightening dinosaur sounds (pounding footsteps, Raptor shrieks, Dilophosaurus' hissing, the T-Rex's iconic roar, etc), as well as environmental sound effects including thunder, rain, and destruction. John Williams' score can also get very ominous and scary at points, adding to the suspense.
There is a T-Rex chase scene. The car goes fast enough to escape the T-Rex but there is a collision and everybody is in danger. In that same scene the car hits a tree and glass goes everywhere. No-one is hurt.
A car falls into a tree with a kid in it. Someone goes up to get him but the car falls down and nearly hits them, but they are all okay.
Most likely gonna give you scares for the first time watching, and most definitely intense if you're a young one. I can imagine this movie being especially frightening back in 1993 in theaters, considering no one has seen a dinosaur movie quite like this before.
The second half of the film is comparatively intense and contains several sequences in which many of the main characters are in danger - mainly from dinosaurs in the park.
A scene where the T-Rex escapes from the habitat includes one onscreen death and an unseen major leg injury. Children are in danger in the scene but come to no major harm.
A scene includes two children who are trapped in a kitchen with raptors hunting them.
People are killed by dinosaurs in very gruesome manners, very intense and somewhat disturbing.
