I just watched it last night. We were having a double feature DVD night and we had just made supper and sat around the idiot box for the movie.
It was a little gruesome in the beginning and put me off my appetite while I was eating.
The fact that humans can oppress anything different from them is a common theme, both in film and in real life.
We may start out with the best of intentions to do good, but eventually it becomes doing bad in the name of good.
I was uplifted by the ending of the movie, and the CGI effects were incredible. It looked so very real. But the transformation of the main character and the alien weapon killing effects were a bit gross, but that added to the realism.
