"Jurassic World: Dominion" has bisected the world, at least the world on Instagram and Twitter into two halves.

One half hates the movie, the other does not care and loves the dinos, the effects, and of course, the fact that Jurassic Park heroes are back to bring it all to a grand closure.

And then there is Chris Pratt, who is not just a new dad but has nearly switched from dad mode to movie-star mode for the premiere.

What has fans excited is the cast. Jeff Goldblum, Laura Dern, Sam Neill and BD Wong are back.

Chris Pratt, Bryce Dallas Howard, Isabella Sermon, Justice Smith, and Daniella Pineda are still here.

Pratt is excited, obviously, as one of his biggest movies goes to town, and fan enthusiasm certainly seems to be on a big, big high.

Pratt took to Instagram, captioning a montage of video clips and photos as "A premiere worth waiting 65 million years for!”

It shows him switching from dad mode to movie star mode as he interacts with the fans and poses for the shutterbugs.

But even so, one comment from him about “tested fans” and masks have put Instagram into yet another tizz.
