WARNING: The following article contains major spoilers for Jurassic World: Fallen Kingdom, in theaters now.
With its surprising ending, Jurassic World: Fallen Kingdom proved that it truly had something different to bring to the franchise outside of a few new dinosaurs, bigger theme parks and hybrid monsters -- it actually added to the fundamental themes and world of the Jurassic Park franchise.
With each installment, the discussion about caution and scientific progress has become slightly less hypothetical in the context of the films. Where it was mostly just a collection of discussions in Jurassic Park, the new trilogy seems to be attempting to bring events closer to Ian Malcolm's (Jeff Goldblum) worst case scenario. It's an allegory that develops the discussion Steven Spielberg and author/creator Michael Crichton began with the first Jurassic Park about underestimating the dangers of progress and the illusion of control. That perspective was interesting, but ultimately simplistic, which is partly why the films that followed were slightly disappointing. In short, they simply failed to develop that discussion. That's why this new trilogy is so exciting, as it attempts to explore the complexities of the franchise's original themes in ways the early films never could.
Jurassic World introduced the Indominus Rex as a means of exploring the lengths to which people motivated by greed and reckless ambition would go to in their search for power. Vic Hoskins (Vincent D'Onofrio) and Henry Wu (B.D Wong) both helped to illustrate humankind's ability to accomplish great scientific feats while Masrani (Irrfan Khan) served as an example of humanity's tendency to overestimate its level of control. With Jurassic World: Fallen Kingdom, that discussion continues as the dinosaurs are brought off the island and sold to buyers from all around the world regardless of intent. Mills did all this purely for wealth, which is something that briefly brings him into conflict with Dr. Wu, which could be interpreted as a way of highlighting the conflict between greed and science.
John Hammond (Richard Attenborough) and Benjamin Lockwood (James Cromwell) began work on resurrecting dinosaurs together. By establishing InGen, it was their dream to unlock new possibilities through genetics and cloning. Although their intentions were relatively tame, even arguably innocent, the scientific advances they supported eventually tore them apart. Hammond refused to use InGen's cloning capabilities on humans, which was something Lockwood wanted and eventually managed to do. Lockwood cloned his dead daughter to create Maisie (Isabella Sermon).
Maisie had evidently always been fascinated by dinosaurs but, despite the harrowing experience she'd been given thanks to Mills (Rafe Spalls), Henry Wu (B.D Wong) and their Indoraptor, Maisie's revelation about her origin seems to have evoked a vague sense of kinship with the dinosaurs since, like her, they were created using InGen's technology. It's why she freed the dinosaurs in spite of the fact that everyone in that room had the opportunity to erase InGen's mistakes completely in that facility beneath Lockwood Manor. As she explained it, "they're alive, like me."
That final act is how Jurassic World: Fallen Kingdom set the stage for something potentially revolutionary in the currently titled Jurassic World 3.
