Toy Story 3 : Cried 3 times, laughed like crazy

Toy Story 2: Cried once, laughed less than 3, more than 1.

I didn't cry at all in Toy Story, and I don't think I laughed as much either. BUT! Toy Story 2 and 3 wouldn't have nearly been as funny or as touching if they weren't able to draw on the foundation that Toy Story created. The little inside jokes, the back story, the references. So I think I got the most overall entertainment from the 3rd one, but collectively it's one of the best trilogies that film industry has ever put out.
