I saw the movie 2 nights ago. I thought it was just okay, actually slightly below okay. I liked "The Village" much better, as the acting was far superior, even though I anticipated the twist better in that movie.
Julianne Moore was overacting, and I felt no bond to her character, more like annoyance. I was more intrigued with the extraterrestrial aspect, but was highly disappointed that the movie didn't go more into depth in that aspect.
Without satisifying the viewer's curiosity about the alien aspect, I think the movie is a cop-out and the plot really is sub-par.
