As for my thoughts on how The Lost World, Jurassic Park III, and Sorna have been treated by Jurassic World and Fallen Kingdom... it's fine. I would have personally loved more references to those films and Site, but I still like what we got from the viral marketing.
From how I see it, the Jurassic World series is a soft reboot. Jurassic Park III came out fourteen years before it. So while not retconning the other sequels from continuity, Jurassic World was going to be seen by a new generation of fans. Many of which have not seen the other sequels. So I can understand the decision to not reference the sequels and Sorna as much as they could have, since they were appealing to a new audience as well as an old one.
I'm not too upset with the lack of references to the sequels and the Isla Sorna. While I would have liked them, they don't impact my enjoyment of the Jurassic World movies that much in the grand scheme of things.
