Unfortunately, I need to preface this by saying that, despite being both sophisticated and dark, this was supposed to be a kids’ movie. It’s a significant consideration because, for some reason, it seems to garner recurring criticism over the supposedly impossible group dynamic.
If we’re going to split hairs, it’s only fair to point out how each person dropped into an unknown world confined by seemingly impenetrable boundaries, was purposefully selected. In fact, it’s clear they’ve been bred, or at least chosen, for some unique quality.
Regardless, no one expects a movie about superheroes to explain where and how they go to the bathroom or to analyze the likelihood of the giant lizard terrorizing the city having Salmonella. At least here, there’s good acting, genuine chemistry and the visual effects enhance the mysterious environment, in which a bunch of random kids are forced to survive by forming a makeshift society. To be clear: this is not Lord of the Flies; it’s actually fun to watch.
