The ending of Toy Story had me bawling like a baby. It was literally like I had to give up my childhood. Passing it along to the next generation. That movie was tailored for those of us who grew up with Toy Story.
Also, during the inferno scene I nearly pissed myself thinking they might actually end it like that, and felt like a kid afraid to see his favorite characters die.
However, my friends and I felt that a happy ending could still come from that, the toys could be melted down and used in plastic for new toys being made and live on in the hearts of children somewhere else.
