I don't know what Bob's talking about, I think the newer feathered dinosaurs look just as awesome as the older reptilian ones. Maybe even moreso.
I guess it is a tad disappointing that Jurassic World decided not to be scientifically accurate in this regard, but it's not as if it's surprising. I would go as far as to say it should have been expected. I can't think of a single Hollywood film in recent history that gets its science entirely correct. Most don't try, because they would rather put energy into being entertaining, because entertainment is the entire point of a Hollywood film. And nobody cares, usually. Nobody lets scientific inaccuracies ruin a good film for them. Nobody hates Gravity because the orbits are wrong, nobody has a problem with Avengers because the Iron Man suit is technically impossible. So it seems odd to me that people would be freaking out about this.
The thing is it's not even a plot hole or anything like that. The fact that the dinosaurs look like this makes perfect sense, because they technically aren't even dinosaurs. According to the first movie, they're mostly frogs, amphibians, which have nothing resembling feathers. Only some of their dna is from dinosaurs. The scientists in the film mixed the two until they got what they thought looked like dinosaurs, which is what we thought they looked like back then. The fact that real dinosaurs didn't actually look like that doesn't change a thing.
Honestly, making the dinosaurs feathery would arguably go against continuity, because this series has already established what their dinosaurs look like, and you can't just change that because of science that happened outside the series' universe. Of course, if they explained why they looked different (maybe they were able to use more dinosaur dna, or they used a different process or something) would easily fix that problem.
