It's actually called "Legend of the Guardians: The Owls of Ga'Hoole"
I loved Happy Feet. I thought they did a good job of giving the penguins distinctive looks without getting too crazy, and giving them facial expressions without getting too cartoon-y, and the detail in some of the scenes was mindblowing. But the storyline was chopped and stopped making sense about an hour in.
The owl movie is done by the same people, but it's only an hour and a half long and based off a series of kid's books. So all the GOOD stuff from Happy Feet is there (minus the musical numbers), minus the bad stuff.
Basically, this is Lord of the Rings with owls, and it fucking rocks. I give it an 8 out of 10 and recommend you go see it.
As evidence, I present:
A Good Owl
An Evil Owl
A Fluffy Baby Owl
And An Owl in Fucking Armor.
There are many things you should not put in beer. Swans are one of them.
