It seems like understanding this movie hinges on an early scene where one of the characters is sporting a Jurassic Park shirt. It feels like the filmmakers were signaling to viewers that everything unfolding is meant to be taken lightly. How else can you make sense of a film in which the main characters arrive in South Africa and immediately complain about the heat, despite being bundled up in jackets, sweaters, and hoodies? Even more puzzling is how to understand a movie that brings up poaching—the act of killing lions—and anti-poaching—which, according to Beast, involves killing those who kill lions—only to have the villain be a lion that attacks people regardless of their views on poaching. This just reinforces the idea that lions are always portrayed as wanting to attack humans (while failing to offer any real insight into the poaching issue). I’m not suggesting that lions operate under an animal version of Asimov's First Law of Robotics, but they consistently get a bad image in films, much like sharks do. In this regard, Beast is more akin to Jaws: The Revenge than the original Jaws. To be honest, Beast is even less enjoyable than Jaws: The Revenge because at least that film used a mechanical shark, unlike Beast’s disappointing CGI lion. Overall, it leaves you wishing for the straightforwardness of The Ghost and the Darkness, which openly presented itself as a simple story about male camaraderie during a big game hunt (and which, despite its creative liberties with the true events, had the courtesy of featuring actual lions). Here, though, the hero manipulates two other lions into killing the 'evil' lion—a plan that could easily go wrong and isn’t particularly considerate of nature. Though, it’s possible these lions are adhering to the second part of the First Law ("A robot [or in this case, a lion] must not...through inaction, allow a human being to come to harm").
