I actually cry at all films, sad or not. 'Up' took it to a different level though - I sobbed pretty much all of the way through it. Towards the end, I was just about recovering. Until Kevin got his badge......At one point during the film, my daughter (6 at the time) told me that we could leave if I was finding it too hard.
I had heard that 'Toy Story 3' had its moments, so I went reluctantly, and prepared. We got past the impending doom bit with the furnace, and I was priding myself on having shed not one tear. Foolishly let my guard down.......because that wasn't it.
