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.
Crowning Music of Awesome: Pretty much the entire soundtrack, containing some gorgeous emotional pieces alongside the brilliantly scary pieces, but a notable example is Mun's mournful violin solo, which plays during a montage of her temporarily becoming a recluse after seeing one too many ghosts.
Paranoia Fuel: There are ghosts everywhere and most of us can't even see them. That elevator you're riding? There's a disfigured old man in the corner just waiting to sneak up on you. That calligraphy class you're taking? You're sitting in some chick's seat, and she isn't happy about it.
Sequelitis: Many feel that The Eye 10 and The Child's Eye are inferior to the first two films.
