What's your favorite part?
For me it's the Tesseract scene, it was so moving when Cooper realized that Murph would go back for the watch because "he gave it to her", that was really powerful.
I also loved the scene where Cooper has to watch the videos of his children growing up when he got back from Miller's planet and there is nothing he can do about the fact that he missed it. Some of the greatest acting I've ever seen and McConaughey didn't say a word.
I really have to hand it to Nolan, he took a bad actor like McConaughey and directed him to an amazing performance.
