This was posted in the “Movies you’ve seen recently” thread, but I thought it’d make more sense to reply to it here:
My interpretation of that:
Jupe lived through it and saw what could happen when you try to tame nature without actually understanding it. And even though he knew the risk, his hubris caused him to do the exact same thing with the alien creature. He thought he could control it, until it ate all the people at the show.
And btw, if you have a chance to see this film on a true 1.43 IMAX screen, go!! It really utilized every inch of that massive screen. I don’t know how they could cut down certain scenes to fit smaller screens, because there were times when the action in the shot was at the very top and very bottom.
