I was never a huge fan of Toy Story 1, but 3 was absolutely amazing. [i]Loved[/i] it. It's absolutely sweet and positively funny. Even if Disney movies aren't your thing, this is a must-see.
The actor who voiced Slinky Dog died about ten years ago from lung cancer. That's why the character had limited dialog; the actor, who I adore, had an amazingly unique voice, and it would not have been the same to have someone else take his place. You may want to adjust your critique of that category.
I have grown up with Toy Story and to watch number 3 brought tears to my eyes right at the end. It's true what you said at the end of your article because Toy Story is one of the films that completes your life. Not many films these days can beat what Disney and Pixar have created.
Overall, great article!
:D
