Why It Rocks

Bad Qualities

 * 1) The film does suffer from being predictable.
 * 2) There are some factual goofs in the film:
 * 3) *When the giant octopus went into The Golden Gate Bridge, but at the shot where John goes to the police car after he took a ride from the helicopter, the octopus wasn't seen attacking on the bridge on the right of the screen.
 * 4) The effects didn't aged well in today's standards.
 * 5) The first half of the film feels almost like a newsreel at the point.
