7. The Lost World: Jurassic Park (1997)
To be fair, following up on Jurassic Park was an impossible task, and, all things considered, The Lost World: Jurassic Park did a serviceable job of continuing the original’s story. However, despite its less than stellar writing being a noticeable step down from its predecessor, The Lost World: Jurassic Park also fell victim to the hopeless staggering of its own ending.
The Lost World‘s plot establishes that another island is filled with dinosaurs, and that these ones all live free. After heading to Isla Sorna to document the creatures in their “natural” habitat (and barely coming away with their lives), The Lost World: Jurassic Park veers sharply into King Kong territory, with its villain revealing that he intends bring a captured Tyrannosaurus rex to San Diego as an attraction.
From there, The Lost World drags on, as the dinosaur inevitably breaks free and rampages around the city. It’s a scene that’s become infamous for how unnecessary it is, and it ultimately ends with the safe capture of the dinosaur and its return to the island. In short, the additional scenes of dinosaur rampage were little more than a set piece intended to fluff out the film, and had no real bearing on its overall story.
