I learned that Doc is the most easily pushed around character in movie history. No matter what he always goes with and does what other people want him to,even when they refuse to tell him where they are going.But there's no time!

I learned that the best way to escape a slow moving monster is not to drive your boat as fast as it can go away from it but is instead to ditch the boat,set it on fire,and then stay in one place not moving hoping it goes away.
