Definitely better than Paranormal Activity 1, part I somehow took an not so interesting turn in the middle of the movie -- when they showed the woman just standing there next to the bed for hours... then you saw the foot prints... I guess it ruins it for me once the monsters/demons/spirits take on a tangible form.
2's "scariness" is more consistent, then again, it's always scary when you combine eerie music and loud noises (probably don't even need the visual). Oh, and 2 is also
educational -- never know there's a difference between "demons" and "ghosts"... probably because all "ghosts" come from dead people in the Chinese culture.
Here comes the spoiler part: The only part I don't get is: if the demon's purpose is to get to the boy, why did it
1) harass the mother (female) when she was a child
2) what's the purpose behind making the pots and pans fell and starting a fire on the kitchen stove (maybe to prompt the mother to give it the son?)
3) moving the pool cleaner? really?
4) the relationship between the demon and the basement? It kept implying that the demon came from the basement... I guess it's the lowest part of the house and closest to hell, maybe?
5) Once it possessed the mother, why not just make her take the child and disappear? Why wait till it was driven into the aunt, then have the aunt killed the parents then disappeared with the child?
So many questions. Yes, yes, suspension of disbelief. :)
