I myself am a fan of Pixar Movies, but these guys really did an outstanding job with Toy Story 3. What I loved from this movie is that it's substantially different from the other two movies from the beginning! It has a certain and interesting sad or "pessimistic" atmosphere that it brings from the very beginning of the movie and makes you think the worse resolution of situations for our beloved characters. Because of this change, I enjoyed every second of this great animation, and this time I assure, I didn't really know what was going to happen.
There's another change that I liked too, and that's the role of every character. I mean, unlike the first and second movies, this third work gave a significant role to all characters, what means everyone had an important task to accomplish in the main story.
Finally, the villains, villains with a sad story, who have a reason to be "evil". That's the type of villain I usually like.
This movie made me laugh, thrilled me and even moved me to tears. That's why I'm giving it a 10/10 rating.
