I saw it last night too and yes there is one scene where I tried my best not to cry. I had read a review that said it was the best moment of the film where Will Smith doesn't say anything, its just a close up on his face.
Overall I enjoyed the movie, I think he did a fantastic job carrying the movie by himself for about 80% through it, the last 20 minutes or so could've gone differently but the rest of the movie made up for it.
I'm heavy into the movies and how they do money wise and I was so excited that he broke some records and made tons of money. Personally I'm a Will Smith fanatic, he can do no wrong in my eyes when it comes to his movies. He's a bonafide movie star and you're guaranteed a good time when you see his movies. He's one of only a few actors that I don't mind spending $12 for tickets and food to go and see. Go Will!!!
