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.

In recent years, Delmar is also popular amongst some film viewers who are also video gamers, due to a form of Retroactive Recognition of the character being played by Craig Fairbrass, who would later being known for his voice acting in the Call of Duty: Modern Warfare trilogy, especially his performance as Ghost from Modern Warfare 2. Some viewers can see Delmar as an Evil Counterpart to his actor's later Call of Duty characters due to some similarities they share (for example, Delmar wears a brown vest like Gaz from the first Modern Warfare game, carries a submachine gun that looks like the very same one Wallcroft carries from the third Modern Warfare game and wears a black jumpsuit throughout the film like Gaz's SAS attire in the first Modern Warfare game's level "Crew Expendable" and Wallcroft's default SAS clothing). Aside from this fact and the comparisons, Delmar is also singled out for being a Bad Ass himself like his Slow Motion kill of Frank, his self-mentioned background as a former soccer player and his unique soccer-kicking torture of Tucker.
Evil Is Cool: Kynette, for being the most intimidating and formidable henchman out of Qualen's group.
Delmar, basically due his actor Craig Fairbrass receiving Retroactive Recognition for his later voice acting in the Call of Duty game franchise, as well as his Hidden Depths as an ex-soccer player in which it contributes to his Curb-Stomp Battle against his hostage Tucker.
Fridge Logic: While providing the movie with enough mooks for Walker to take down one by one, you have to wonder why Qualen needed at least five heavily armed mercenaries who's sole role during the airplane heist would have been nothing but to sit around if it had gone according to plan.
Iron Woobie: Walker, he is overcome with grief from his failure to save his best friend's girlfriend, captured by Qualen's goons who stripped him of his jacket and bolt gun that left him vulnerable to the cold and finds himself a living target for the villains to hunt down.
Jerkass Woobie: Tucker, as he blames Walker for his failure to save Sarah, which is understandable as Sarah was Tucker's girlfriend and Tucker loves her so. He becomes more of a Butt Monkey later in the film when is forced to be a guide for Qualen's posse, bullied around, Forced to Watch them kill two of his colleagues that he later protested against before being on the receiving end of a No-Holds-Barred Beatdown given by one of Qualen's goons.
Moral Event Horizon: Renny Harlin makes you hate Qualen and his fellows so much that you'll cheer when they all meet their ends.
Narm: In about half the death scenes, you wonder if Renny Harlin thought he was making an Oscar BaitTearjerker rather than an action movie.
Speaking of which, Frank's facial expression during the failed rescue scene at the beginning was off, like he was smiling...
Nightmare Fuel: Sarah, Tucker's girlfriend, meets a truly horrific demise at the beginning of the film. Her climbing rig malfunctions and despite Walker's best efforts to try and save her, she plummets to her death.
