It's as good as you've heard. In fact, it's quite brilliant. It's as hugely satisfying, eminently enjoyable, and as expertly crafted as you'd expect from the folks at Pixar. You will laugh. You will cry. You will feel warm and fuzzy on the inside. You will wonder why all films can't be like this.
I could go on and on about the exquisite detail in the animation and how the script is so beautifully layered and nuanced that it scores on every level and for every age group. I could, but I won't. All I will say is this, if you haven't seen it, see it. And if you have, well, see it again. I know I will.
