I agree with Sean in that this is an amazing movie.
Every action has a reaction, but you never know what the reaction will be until the action has taken place. But what if you don't like the reaction? What if you could rewind make a different action to cause a different reaction?
When it comes to the lives of your friends, your family and even yourself, wouldn't you want to keep rewinding in order for everything to play out right?
As you are watching this movie, many parts of it won't make sense. However as it plays out in it's entirety everything drops into place.
A must see!
