Jimbo’s review published on Letterboxd :
Another cracker from Pixar, the opening 20 minutes is the saddest animation you'll see, the rest is joy and without ever coming over as schmaltzy. Technically, the detail is phenomenal, the reflections, the hair, the materials, every surface is flawless (in the 2D version I saw at least). 2009 was a year in which I saw so many good movies, this beats the lot. Squirrel!
