I adore the idea with Evil Dead and I've said elsewhere on these forums that's what I would love to see happen with Friday the 13th.
But for an IP as big as Jurassic Park/World? I'm not sure that'd be where I'd go. It's one thing to let new voices play in a sandbox that'll cost you $10-15 million to make. It's an entirely other one to let them run free with a $150+ million budgets.
Honestly, reading the original Crichton novel for the first time currently, I would love to see a more faithful adaptation that takes a limited series approach (4-6 episodes, 6-10 hours long sort of deal) that has more of a straight forward horror bend to it. But you can't put a limited series in theaters and make $300+ million on it from the box office so that's a pipe dream.
I'd say a reboot but for who, for what? They can't stray too far from the tried and true because I don't think the masses would accept it but on the other hand it's tiresome seeing the same 'wonderous beauty' scene in every other Jurassic film.
All of this to say I'm trying to solve a problem that Universal wouldn't really even see. Rebirth is doing well and will likely do very well overall box office wise so they likely don't see a problem with the current model. I just personally think there's a chance to create a film as masterful as the original JP, they just need to take their time with it.
