One of the things I love most about these films is how simple they are. They do not have big expensive sets or waste a lot of money on make up. They rely on things like music, lighting, sound, good acting and a clever script to build up tension.
I hate horror films that are nothing but blood baths or ones that use too much computer animation or bad rubber masks. One of the things I found the most scary about the first paranormal activity film was their clever use of thumping footsteps coming up and down the stairs. So simple, so effective...so bloody scary!
There's been four paranormal activity films now. I still enjoy them...despite their flaws. They've written themselves into a hole and they know it. Every film is the same as the last one: some weird stuff starts happening in a house, the occupants freak out and start filming it, the activity gets worse...eventually resulting in the death of one or more of the people in the house.
The people behind these films sure do know how to keep people coming back for more. They are experts at dragging out the plot. It's very frustrating. Each film always reveals something new...and leaves more questions begging to be answered. These films are a lot like the tv show "LOST" : lots of good ideas get thrown around, crash into each other, fall over...and nothing really gets answered.
And yet I still like them. I know the writing is not the best (and at the same time is still clever), but I don't care. These films are like popcorn. Good, silly fun. I hope they stay good and don't turn dumb like the Scream films did.
