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.
Designated Hero: Really, the entire conflict of the movie is pretty much Joe's fault, as he doublecrosses the Irish in order to steal Gorgo for himself and use him as a circus attraction to strike it reach. Sam is a lesser example, as while he doesn't bat an eye to Joe's plan to doublecross the Irish, he does object to Joe's more sleazier actions such as trying to abandon Shaun and later insisting that Gorgo be kept locked up even when they learn that his mother is on her way. He's also generally far more pleasant and moral than Joe, especially towards Shaun.
Fan Nickname: Gorgo's mother is sometimes called "Ogra" (though it's pronounced "Oogra") after the mythic name for the beast mentioned at the start of the movie.
