I really love this movie. The disability theme is used really well, and I honestly felt any positive impact that this movie may give to anyone that ever felt like Dory will be enough to justify it's entire existence.
Hank and his overall done-ness with the world is amazing, and I certainly won't blame Pixar or Stanton if they ever decided to make a sequal/spin-off focused on him. Plus, I will totally watch that.
The climax is great, despite being humor driven instead of emotion driven like Pixar's strongest efforts, and seriously, that part with the falling truck is one of the most hilarous thing that Pixar have ever done.
