Toy Story 3 was a fantastic film, a brilliant, moving end to the trilogy - one that I don't think any other series has ever come close to. Not even Lord of the Rings was able to generate as intense emotions in the crowd; it was all too 'fantasy' and epic - it lacked the human scale.
As the OP says, I found the film really connected with my childhood, especially having grown up with the first two films - and unusually for a trilogy, I'd definitely say that this final part was the best, though probably only if you'd seen the previous ones to establish and develop the characters' histories.
