Well if theyve unsettled the viewer then they are unsettling. They may not be to everybody but i kinda agree. Thats why i though the new raptors in JP3 where rubbish. Yeah they where closer to reality and what we know about raptors but those big, bulky raptors with their piercing stare from the first movie are really creepy. Theyre unsettling because you get the sense that they are just as smart as you. In JP3 they just felt like animals, in JP they where presented as almost like a serial killers.
