Jurassic World Director Says There Should Only Have Been One Jurassic Park Movie (But He's Planned More) - IGN - IGN

In a recent interview with Empire magazine, Trevorrow suggested Steven Spielberg's Jurassic Park was an "inherently un-franchisable" movie that probably didn't warrant any sequels, so in order to forge a new path for the franchise to continue, it was important to evolve the series and find fresh opportunities for where it could go, especially after Jurassic World Dominion.

"For the franchise to be able to move forward – because it's inherently unfranchisable, there probably should have only been one Jurassic Park – but if we're gonna do it, how can I allow them to tell stories in a world in which dinosaurs exist, as opposed to, here's another reason why we're going to an island?" he said, explaining how he adjusted his thinking for Dominion.

After changing the DNA of the franchise and shifting focus to a story about characters coexisting with dinosaurs, Trevorrow said he spoke to Universal about where the franchise could potentially go next.
