Dinosaurs don't have feathers in the general imagination of what dinosaurs looks like, it doesn't really matter if the scientific consensus at present is that they actually did. The first Jurassic Park was obviously interested in the wonder of actual dinosaurs. Imagine if we somehow managed to resurrect dinosaurs and could marvel at them, like we do other imposing animals we put in zoos and film for wild life documentaries, etc? The film wanted to inspire kids to get interested in dinosaurs, the history and science of the real thing.
I haven't seen Jurassic World, but it from what I have read it seems the film posits dinosaurs simply existing is a bit boring, and the park arranges events (raptor fights?) that draw an audience. Now, you can take this as a swipe against the movie going public or whatever, but at the very least it certainly makes clear it's aspiration to spectacle rather than awe.
I would personally have loved to see dinosaurs with feathers, not for scientific accuracy, but because it would be a cool new way of imagining dinosaurs.
