The camera is great! It adds to how real it felt. Also I can't help but half-laugh and pause at the people who saw it for the first time back when everyone thought it was real and they're sitting there, thinking this might be the last footage shot of three missing people, and thinking, "mm shakey cam no likey".
As for today I hate seeing some people making fun of it and deriding it as 'terrible'. Even if you go back and watch it now, it's all great. It feels small, it feels homemade, and that's the point.
