...just back from seeing it a little while ago.  Lots of sniffling as people leaving the theater.  (Not me)  But I did like it.  It didnt leave us hanging with "Gee, how'd it end".  Nice begining, good story, and nice ending.  I won't ruin for others, but I thought it was great.
It was a thinker.  I'm kinda burned out on the flashy action/gee-whiz stuff.  By my estimate, the movie was a wee on the long side, but to shorten it would have sacrficed the nice long ending.
If you sat thru and liked "Contact", you'll like this.
