I LOVED this movie. Going in I was hesitant because I was afraid that the dog would be the one to die. (I can't bring myself to watch Old Yeller or Bambi for that exact reason.) I was touched, moved, made to giggle and laugh out loud as well as shed tears willingly. I'm not into sci-fi but was absolutely captured by the humanity. Tom Hanks should be an Oscar contender for his performance. And Jeff. WOW! Kudos to the writers and the magicians who brought Jeff to life and into our hearts. I recommend this without hesitation to anyone.
