This is my problem with a lot of screenwriting tips and discussions. In my opinion, there are no rules to how a screenwriter has to portray anything. If they feel it's in service to the story, that's their prerogative. Besides, one can't always look at each element of a story and try to explain every jot and tittle about how it pertains to the picture at large. In life, things happen, and sometimes writers include them. This death scene never brought me out of the film. I did look at my girlfriend in awe and talked about how horrible it must have been for her to die, but it didn't remove me from the ride that is Jurassic World. Besides, this scene was probably foreshadowing to the final scene of the film anyway.
But let's go out on a limb and just for fun say that this film exists and the events portrayed actually happened and this character died exactly like that. You can't blame god/nature/whoever for killing this person in a way that didn't really feel justified to the overall news story about the incident, can you? Sometimes terrible things happen. Just because the writers chose to show it doesn't mean that other people didn't die in as gruesome ways.
I try to write as if whatever I'm writing is real. I try to develop my world and the causes and effects the story create within it. After that, it's all about what I choose to show.
The Jerk was a notable favorite of Kubrick as well.
