When I watched it when it came out about 6 years ago and I was 12ish, I remember hating it because I thought it was a scary movie and it wasn't at all. Gave it another shot now at my age and it definitely was a better movie.
When M Night Shamalama puts trailers out of his movies being scary when only a small percentage of the actual movie is meant to be scary, I think it really leaves a bad taste in the mouths of viewers.
