Chicken Run

I can't stop comparing stop-motion films like Wallace & Gromit and Chicken Run to WW2. (Which for Chicken Run makes sense since it's a spoof of The Great Escape).

Clever storytelling and genuinely funny. The animation is great (as usual for Aardman), and the characters are super fun to watch. Even though the message of environmentalism here isn't necessarily great, the alternate theme of never giving up is portrayed well.
