I know that Disney/Pixar usualy makes movies that can pull some emotion out of the coldest of people... however this movie was done no justice by the previews.
I don't think I have shed this many tears in a movie, EVER!!! This movie was one of the best movies I have seen in a long time. The emotion behind the main charecter was amazing. The opening montage, without a single word being said, had eveyone in the theater weeping. Don't expect to walk in and out of their being depressed. This movie has plenty of humor that you would grow to expect from a Pixar movie.
You will walk out of this movie refreshed and with an outlook that you just can't take things in life for granted.
