Quoted from accidental:

You're right that GoT is more popular than ever, but it is still a Shadow of the popularity of Jurassic World. JW broke $1 billion at the box office in two weeks. GoT finales have viewerships of 8 million (to compare, assume each GoT finale viewer bought a $8 movie ticket, which is $64 million).
You could make a compelling argument that being an ongoing series GoT is more likely to have sustaining interest than a one-off film. But when you consider the record-breaking success of JW that was a huge 14 year gap from the previous entry in the series also proves that JP is about as evergreen an IP as they come.
