So are you reviewing the movie itself or are you trying to preach an environmental message?
If you are reviewing the movie itself, why not talk about how well it entertained? Was the acting good? was the comic timing up to par? Was the setting good? I find it very interesting you found the first half boring. The first half was the romantic comedy type party between Audrey and Ted and the second part was all about the environmental preaching. Romance is boring, yet the accusing finger is interesting? I'm sure there are people who might disagree with THAT.
If you're trying to preach a message, I hate to rain on your parade but the what works in the movie such as the "in your face" approach you mentioned, rarely if ever works in the real world. How many times in the past has the accusing finger ever been popular?
The issue today is no longer pollution caused by toxic chemical wastes and other forms of waste but global warming which is caused by, of all things, according to the activists, the natural substance carbon dioxide. What's more, the science on global warming is hardly conclusive. Carbon dioxide only rises AFTER the earth's temperature rises. There is no DOUBT pollution is conclusive. You can see pollution when it's there. To believe that global warming exists, you have to TRUST the scientists.
In addition, the Lorax only accuses big greedy corporations and the issue is pollution. Today's environmental groups take the accusations a quantum leap further. They accuse EVERY private business, greedy or not, and NOT because they pollute the planet but because they are private businesses period. Not only do they accuse private businesses but every American citizen because they are part of the "capitalist system". There are some who would call that bigotry. Certainly bigotry is not something Dr. Suess would have wanted.
Evidently, socialism is supposed to be the answer.
Now I have been to other countries and at least in comparison, America is far cleaner than most countries, even socialist countries. Yes, there are still states with a lot of smog, however, in general, the US is certainly cleaner than China, or even most countries in Europe.
These days the environmentalists themselves are involved in bribery scandals (climategate and others), and it seems the REAL goal is money and power....not too unlike the very greedy corporations the Lorax was trying to finger.
You are definitely right about one thing. The "trends are not promising", However, I believe in the "unless" message. The message of the environmentalists of today WILL be ignored and probably laughed at UNLESS the message goes back to being that of pollution and UNLESS the environmentalists begin to show they are on the side of the average citizen.
