I saw this movie with my friends, and by the end we were all a mess. My friend cried through the whole movie just by knowing the fact that Andy was going to college and the toys needed to figure something out. A great movie. Its more focused on teenagers moving on to college or in high school years. Kids might not get the whole college part of the movie.
I must say this movie extremely disappointed me. I was looking forward to something like the past movies, action, a little bit of humor mixed in, and some talking. However this movie was all about getting girlfriends/boyfriends and there was barely any action and it was all talk. I must say this would disappoint people who have read the book because a lot of parts were missing and it would disappoint those who are used to the good old harry potter movies (1-6).
For me, I think you need to see the first movie in order to get what is going on. I have seen comments saying there was no character development, but all the characters were well developed in the first movie It was very good, lots of action, few shrewd jokes thrown in there, and the CGI was very amazing.
