I personally couldn't stand this movie lol. It actually looks really good from the trailers, but like you said when you actually sit down and watch it, it has no plot. I mean, I kind of understand what it was trying to do, it was trying to show the history of all life and show that we're all interconnected or something, but in my opinion it really failed. If it just had some consistency rather than a jumbled collection of unrelated scenes (not to mention the super-creepy whispering going on through the whole movie) it may have been ok, but as it is I found it rather un-enjoyable.
