I absolutely loved this from beginning to end. My wife and I are huge pixar nerds so we were already in the "it'll be good" mindset but I had no idea just HOW good it would be and I must say, I think this is the best of the 3.
I think it's by far Pixar's funniest movie and also probably the biggest tear jerker they've released. Everyone knows how it has to end and it's tough to watch and keep it together but they end it on a happy note (not going to spoil anything).
Whether you have kids or not, this is a must see. It's non stopped action and laughs from beginning to end.
Highlights for me would be the barrel of monkeys bomb, tortilia potato head and best of all, spanish buzz lightyear. Those 3 had me in tears laughing.
