I say this is a worthwhile movie to watch. I really enjoyed it. In the cinema I was in, it was only half full. At the end a group of people gave an applause, and as the credits rolled, everyone that were already leaving stopped to see the last scene. Normally if it was an average movie alot of people would just keep moving to the exit.
I enjoyed all the characters in the story. The apes in particular were great as I could feel for them. In the end I felt sad, as if this movie could of been based on a true real life story. I just found it so believable.
