Just got back from the movie, I'm really surprised nobody else has mentioned this.
I wasn't expecting a 3/4 full theatre, thinking that most people aren't penguin freaks like I am. But this movie really seems to have taken off.
All I can say about this movie is GO SEE IT ... NOW!!! There are no special effects, no human actors but there is more emotion in this movie than all of the current slate of summer movies combined. It's absolutely amazing what these animals go through every year. You will laugh and cry throughout the entire movie.
Why are you still reading this? Go ... NOW!!!!
