Currently #19 on IMDB's top 250 movies of all time. I'm OK with that.
And, really, just go see it if you haven't.
I won't bother to summarize the plot, if you're at all sentient you've picked it up already. After movies with talking toys, bugs, monsters, fish, superheroes, cars, rats, and robots, Pixar chose to make a movie where the protagonist is an ordinary guy. And not even a traditional hero kind of ordinary guy: a grumpy, creaky old guy, widower Carl Fredricksen. That's brave.
And, although I'm unsure how well that might go over with kids, it worked just fine for me. There's lots of fun, but (as you may have heard) the opening few minutes are truly tear-jerking, as the premise of the movie is established by describing how Carl met and (eventually) lost his beloved wife Ellie.
Consumer report: Mrs. Salad and I splurged on the 3D version. Pixar doesn't stoop to any cheap gags, so the 3D experience, while noticeable, isn't in-your-face. So, paradoxically, you might not want to blow the extra money. The power of the flick doesn't lie in the 3D gimmickry.
If you've seen it, there are fun facts aplenty here. (Like: why don't the people have nostrils? And: where was the Pizza Planet truck? I missed it, so I'll have something to watch for when I snag the DVD.)
And Toy Story 3 is (as I type) a mere 366 days away. I'm in line already.
