I thought it was a bit slow but an great story to get discovered.

I thought the movie moved a little slow, but I understand having to build the plot once it was revealed. I enjoyed the twist at the end as the pieces were being assembled.

I appreciate the fact that it was on the opposite end of the alien movie spectrum from "Independence Day" etc., but it was terribly slow and I just didn't care that much about the characters so there wasn't much of an emotional impact as some other reviews suggest. Amy Adams is great, though.

The acting was great however the movie was hard to follow at times. It was hard to tell if Amy Adams character was viewing the past or the future. I thought the movie had a good message.
