I did not cry. I liked the movie, but I wasn't crazy about it. Let me start by saying that I am a big Peter Jackson fan, but I think he go carried away with the CGI thing and left some pretty big holes in the plot. IMHO the scene with the T-Rexs and Kong in the jungle went on too long. I didn't like the bug thing, but that was because I don't like bugs. I was disappointed that there was no wrap up about the ship's crew or how he got Kong back to NY. I also thought Jack Black's response at the end didn't work. How many times did we have to see that same look on his face? I thought he should have had more emotion over the fact that Kong had escaped, was killing people and the fact that Jack Black's character's career was basically over. On the other-hand, the CGI was very good. I thought the acting was good for the most part. I did have to get up twice during the movie to visit the restroom. I'm getting to old for these long movies!
If you want to cry, see "The Family Stone". Wow. That was real tear-jerker!
