The first Jurassic Park film was an adaptation of Michael Crichton’s novel of the same name. Notably, The Lost World: Jurassic Park was also loosely based on the novels, with Jurassic Park III being the first film in the franchise not directly based on the novels. Interestingly, it’s also the first film not directed by Steven Spielberg, which explains why it feels so drastically different. The Jurassic World movies are, naturally, also not based on the books, though they’re full of hat-tips to the originals, making it easy to appreciate the story they’re trying to tell.
There’s a lot that could be said about the plot holes in the Jurassic Park franchise, as while we adore these movies with all of our hearts, there are some details that slipped through the cracks. It’s inevitable, especially when adaptations aren’t directly one-to-one. That said, these three points are arguably the most annoying.
1) Jurassic Park – How the T-Rex (Stealthily) Got Into the Building

Who could forget that amazing conclusion to Jurassic Park, when the T-Rex charged in at the perfect time to (unintentionally) save the humans from the Raptors? It was a huge moment, but it also doesn’t make a lot of sense.
Seriously, how did the T-Rex get to the visitor center? It would have had to go beyond every set of gates, which is admittedly more plausible than not, thanks to Dennis. From there, it would have had to make its way to the visitor center at just the right time to find a tasty snack.
There’s another problem with this, as the film made multiple points of telling viewers how loudly a T-Rex stomps. It’s enough to make nearby water cups shake, as a reminder. So how did the T-Rex get so close without anybody hearing? While the humans may have been distracted, it seems unlikely that this much noise would have been ignored by the Raptors.
Finally, there’s the obvious question of how the T-Rex got into the actual building. Yes, there’s a gap in the back wall, and we’re clearly meant to believe that was the entrance the T-Red used. However, it’s a relatively small hole, especially when compared to a giant T-Rex.
