These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
While retrieving the phone, a Ceratosaurus approaches to the group. It's a pretty big predator and the audience expects to attack, but it merely sniffs the heroes, smells the Spinosaur dung on them, then leaves.
Badass Decay: When the T-Rex shows up to fight the Spinosaurus, two enter, one wins...and the T-Rex goes down in less than a minute, it's attacks barely even damaging the Spinosaurus.
Never Live It Down: The T. rex vs. Spinosaurus scene. Dear,god. In every conversation having to do with this movie, someone will always bring up the scene and complain nonstop about it.
Older Than They Think: The Spinosaurus has been in Jurassic Park merchandise before - as a raptor-like predator in a spin-off fighting game, and a toy - but both had completely different designs from this film's spinosaur.
The Scrappy: Amanda Kirby is probably the least popular character in the series for her frequent screaming and general idiocy on an island full of predatory dinosaurs. Paul isn't much better. Not to mention, both are outright liars who deceive Dr. Grant into taking them to the island.
Villain Sue: It may not be evil, but the Spinosaurus is this in a downplayed sort of way. It easily kills the all time favorite T-rex (which is unlikely in real life), constantly finds the main group, survives being shot at and being hit by a plane, and it doesn't die at the end of the movie.
