Good solid good vs. evil plot and will always work when told with imagination and sincerity. Some complain that an ex marine wouldn’t turn on his former comrades. They are mercenaries, not military. Marines know right from wrong, good from evil, and have very high morals. Well done. And you can always count on left loony Hollywood types to blame the "bad" corporations for the alleged destruction of the Amazon Jungle etc. No one said the bad guys were from earth, but you are led in that direction until you really look back to the story. A long film, but one told so well that you don't want it to end. We saw it twice, in 3D, and enjoyed it as much the second time. A masterful film that is the new standard in visual and sound presentation.
