The graphics were supurb. Someone in the design department is a scuba diver, since many of the "plants" in the film are basted on corals found in our seas. The story line is so anti military and pro treehugger, it becomes distracting. There is litte developement of the characters except for the two leads. You don't care when the "chief" and other characters die.The 3-D effects are wonderful to go along with the graphics, but I could have enjoyed the movie more without the political bias.
