Ending Scene
Similarities
In both stories the protagonist realize the wrong in that they are facing, either a monster or a dinosaur. They leave the place where the conflict was occurring and learned from the problems created.
Differences
The difference is that when Frankenstein ends both the protagonist and the antagonist are dead because of the conflict. In Jurassic Park only the antagonist is dead because of his own greed in money and power over the people he doesn't like.
