Not only is this movie about 10-15 years too late it is also a propaganda movie to intentionally push the pro-environmental message. Whilst I do think this is a god message to push, I don't like it when it is hitting people in the face.
Also, it completely ignores a previous moment in which the same point was made in a funnier episode of this series which just makes this movie all the more pointless.
That said, I've not actually seen it but I do not have high hopes, for
The Simpsons.
