I agree that the script isn't very good in Avatar. There are some really crummy, hackneyed lines in the dialogue. The movie was so strong in other areas, however, that it managed to become a great movie regardless of the primitive script (in my opinion).

Keep in mind that I have never seen Ferngully. ;-)

Jack - Why on Earth would anyone even start watching a movie called "Kickass"??? You must be a glutton for punishment! ;-)
