What a shock, the US is the last to get this....
It pisses me off how Americans are the last to get uplifting and environmentally-friendly entertainment like this. I guess it is because they feel like it won't sell to most people here who would rather watch people blow s**t up.
So, they wait and release it on Earth Day, to make it more appealing to gas-guzzliing, hypocritical jackasses. (And I can say all this because I am a born and bred American, and I can say what I want about my own hypocritical culture.)
