This movie doesn't deserve such low rating
I'd say the true rating would be about 5 or 6. I mean far worse movies get grades like 7 and 8 here on IMDB, but this is now in the IMDB bottom 100? Yes, it's a silly movie with bad animal effects, but I still had a genuine laugh at moments.
Furthermore, this movie identifies the damage that suburban development causes in forest ecosystems. This topic is not new and the American public probably at this point is already tired and hostile toward this type of preaching, but it doesn't mean it's not true. The movie also parodies the so-called Eco-friendly trend that corporations today have adopted just so their activities look nice in the public eye. I'd say it's a good message. Why then this movie is met with such hatred? Because maybe too much people recognized themselves in the caricatures on the screen?
