I was actually surprised at how emotional I got toward the end. The part that got to me more than the finale was actually
The scene in the incinerator where they all hold hands and face the possible end together. Wonderful work by the animators to convey such emotion. This is by far the BEST Toy Story of the three.
That really got me too. I heard the ending was a tearjerker, so I was thinking that might have been it!
