- Gracious alive, this film is every claustrophobe's worst nightmare. If small spaces weren't enough, add zombies to the mix!
- The last 20 minutes or so of the first film are uncomfortably tense and fraught with terror. Think of it this way: You're stumbling around in pitch blackness, dependent on the night vision on a single video camera in order to see any of the bad things you know you're locked in the building with... which are all demon-possessed rage zombies. Next thing you know, you're stuck in a cramped, cluttered space, hiding from the line of sight of a murderous creature that can and WILL kill you, knowing that one single squeak or bump can send everything crashing down on you. Sadly, because it's dark and you can't see a thing while sneaking out, it doesn't work. Sweet dreams.
- The Medeiros girl. Emaciated, tall, animalistic, and possessed by demons. Her silhouette is all too menacing, and her silence before she spots the protagonsit doesn't help.
- Any time Jennifer is shown after she becomes infected, especially the way she just suddenly appears behind everyone else as they're looking for her.
- [REC]3: Clara becoming an infected and ripping out Koldo´s tongue and lips as they kiss. It even becomes worse by the fact that they are immediately shot and killed by the soldiers who are surrounding them.
- [REC]2: The infected children.
- [REC]2: The final shot (before the flashback) has the possessed Ángela staring directly into the camera, smirking evilly, before the film cuts to the flashback.
