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.
Ewan McStarley is a Sociopathic Soldier who was on death row for burning down a village and raping/torturing/murdering its inhabitants. When he's placed in a death match on the island, he happily agrees with the producer to "put on a good show" by doing his usual thing for an audience. He initially teams up with another contestant named Saiga, with whom he attacks Paco and breaks his knee, chains him up, and forces him to watch McStarley beat, rape, stab, and blow up his wife. Then he tracks down the wounded Paco, brutally beats him with Saiga's help, shoots him with an arrow as he lies helpless, then sets him on fire. When all other competition is dead, he turns on the camera crew filming him, and kills them to steal their weapons. As if that weren't enough, near the end of the movie, he machine-guns the crew of the show except Breckel, who escapes the slaughter.
Don't Shoot the Message: Production company hypocrisy and character's sneering aside, Ian's answer against the reporter's Think of the Children! (that people, not broadcasters, should be more vigilant of what kids watch, especially if it's something more controllable by the parents like pay-per-view events) is somewhat accurate.
Harsher in Hindsight: Goldman at one point claims that he would feel safer if the condemned were not so close to them during the games. Fast forward to the end, McStarley kills everyone in Ian's crew, excluding Ian and Julie (Goldman was killed just before that happened).
Tear Jerker: Everything involving Paco and Rosa. They're, along with Jack, the ones that don't care about the game at all, and both only cared about being together while waiting for their eventual death. So, seeing Rosa being raped and eventually killed by McStarley and Saiga while Paco is Forced to Watch, and later Paco being tortured for hours by the same guys that killed his wife before being killed in cold blood, is really sad.
