I seen it a few weeks ago. It made me kind of angry with the characters actions. I too, was dumbfounded with the way a team of scientists reacted on a new planet wit new organisms. It's things on this planet you wouldn't touch, let alone on some unknown planet. People aren't that naive. While watching it, I did think of religion but not to the degree that was really represented in the movie. I'll have to see it again. There's a pretty good breakdown of it on YouTube. The guy "RallisP" goes chapter by chapter on it. He does makes assumptions and comes off as cynical at times.
I don't know how to embed the video. Sooooo.....if someone can do it for me.
