"The Ruins," based on Scott B. Smith’s novel and directed by Carter Smith, avoids common pitfalls of horror films by resisting the urge to go overboard with its thrills and "monster." Films that rely on excessive spectacle often end up being more comical than frightening; “The Ruins” steers clear of this trap, especially noticeable in how it handles the ending, which differs from the book and feels like an improvement. The believability of the situation is what ultimately makes the film effective, a quality supported by the performances of the five central characters. The cast includes Jonathan Tucker as Jeff, Laura Ramsey as Stacy, Jena Malone as Amy, Shawn Ashmore as Eric, and Joe Anderson as Mathias, the German tourist. Ramsey, Malone, and Tucker particularly shine. I found these characters to be relatable and surprisingly well-developed for a ninety-minute horror movie. They aren’t typical reckless college students often seen in this genre; instead, the film reveals aspects of their personalities throughout. While some viewers find the antagonists unconvincing, that's actually a deliberate choice. Similar to “The Birds,” the film transforms something ordinary and non-threatening into a source of horror. Certain scenes are particularly memorable, such as when Stacy and Amy venture into the dark interior of the pyramid searching for a cell phone signal. Their discovery is shocking, surreal, and captivating. Another impactful sequence involves Jeff and Eric performing a disturbing medical procedure. The film’s climax also delivers suspense effectively. Despite being set on the Yucatán Peninsula in Mexico, filming took place in Gold Coast and Tamborine Mountain, Australia, south of Brisbane. Regardless of the location, the scenery is impressive. Overall, “The Ruins” was a pleasant surprise given its low ratings and negative reviews. It’s an adventure story blended with psychological horror that uses something familiar to create fear. The film features decent gore, striking visuals, strong performances, and competent filmmaking overall. It also benefits from Laura Ramsey's presence and avoids the cartoonish elements that plague many horror movies. “The Ruins” delivers on its promises. The theatrical version runs ninety minutes, while the unrated edition is ninety-three minutes; I watched the latter. My grade: B+/A-. [SPOILER ALERT] The plants inhabiting the pyramid raise a thought-provoking question: The animal kingdom ranges from simple organisms to humans. But what about plant life? These plants represent an advanced form, working together to obtain sustenance and even mimicking sounds like human voices and cell phone ringtones. I’ve heard complaints about the protagonists making questionable decisions. However, they trusted Mathias initially, wanting to explore Mayan history beyond typical tourist routes. When Native people appear and fatally shoot one of their group, the pyramid becomes their only refuge; they are then trapped because the ruins are surrounded. How can that be considered a poor choice? Some viewers question why the characters don’t attempt an escape sooner, claiming it's illogical. They remained on the pyramid for two nights, awaiting rescue. Their alternative was to try and flee into the jungle, which was impossible given the Native people surrounding the structure with weapons and their willingness to kill anyone infected by the plants. Waiting for assistance seemed like the most sensible option, and a desperate escape attempt only occurred when necessary. That seems logical to me. Another criticism suggests the characters lack depth. I found them likable, as previously mentioned, and there are numerous instances that reveal their personalities: They desire cultural experiences rather than just partying on vacation; they refuse to abandon Mathias in the pyramid, with the women risking a dangerous descent via rope; Jeff insists on performing a gruesome amputation, even though it makes Eric sick; and Jeff ultimately sacrifices himself so Amy can escape, who then makes a courageous attempt at freedom. This all demonstrates character development. The criticisms directed at the film are largely unfounded or easily explained.
