Which ending is sadder? this or Toy Story 3?

Hands down the Little Mermaid. The only that was sad about Toy Story 3 was the very end when Andy gave up the toys. But with Little Mermaid so many things sad: the music, Fritz overheard Marina made the deal with the sea witch, the Prince got married, Fritz's reaction when he found out that she's going to die (that was the hard part), and that Marina died.

Is this a serious question? Toy Story 3 was more about nostalgia and growing up. It's a little sad, but it's a bit happy, too. The Little Mermaid is just tragedy through and through. It's a beautifully sad ending. A kid growing up says goodbye to his toys vs. a girl dying because of her love, leaving behind not only the man who now realizes who she is but also her family and friends. Which do YOU think is sadder? Lol.

"Despite everything, I believe that people are really good at heart."

The Little Mermaid by leaps and bounds. Toy Story 3's ending was more bittersweet if anything.
