Ending is weak

Rating: Null/10 (15 August 2011)

There are several scenes that are very rewarding as a viewer. One that stands out is when the attack is on the bridge and a horse come galloping up and appears to be empty but the leading chimp is on its back. Another is when the father character is heard playing the piano beautifully only hours after getting the special cocktail. I wish another actor was picked as the female lead. The woman chosen was so weak and benign....I also had a problem with the ending. The movie has so many excellent qualities but the ending is so weak. They all go to the Redwood forest and live happily ever after? The father character goes into the forest and accepts that his adoptive son is 'home'. It is so weak and unsupported by the storyline. What do you think?
