I can't decide one way or another if its a bad thing or not.

One the one hand, yes they should be feathered in order to keep with modern scientific understanding, but at the same time there needs to be continuity between the film. As Grant says in JP3, these are not true Dinosaurs, they are "genetically engineered theme park montsters."

Their DNA was tampered with, altering how they were born. T. rex, Triceratops, Parasaurolophus and Stegosaurus came out okay, The Raptor and Dilophosaurus not so much.

The Dinosaurs were not meant to be able to breed, but the frog DNA that was added allowed them to change genders and breed. Is it too much of a stretch to say that that same DNA negated their ability to have feathers?

It could even be a point discussed in the film. Someone asks why there are no feathers, someone else explains about the DNA and ta-da! problem solved.
