I’ve never given this movie consideration because it looks so retarded.  I saw it high up on a list of the top 100 children’s movies and was surprised… because it looks so retarded.  Well, I saw it at the library today; it’s rated G so I checked it out.  I started it for my kids about 20 minutes ago.  
I’m stunned.  This is a stop-motion claymation twist on The Great Escape, with chickens.  The references to The Great Escape are numerous; nearly everything about it is based on WWII POW escape strategies and stories.  Even the main character’s coup is #17. 
If you have kids, I recommend it.  If you’ve seen The Great Escape a dozen times, I recommend it.
