Cloudy with a Chance of Meatballs opened deservedly well at the box office. I have heard that the movie bears little resemblance to the book but even as a standalone story it is a good family film.
The writer-directors, Phil Lord and Chris Miller (who are friends of the strip), delivered an excellent story about underdogs following their dreams with a palatable portion of warning against gluttony. The animation is top-notch and the voice talent is excellent. I really enjoyed the cultural references like Star Trek, Star Wars, and Fantastic Voyage. (Keep an eye out for the Welcome to Mooseport shout-out.)
If you liked Meet the Robinsons then you will probably like Cloudy with a Chance of Meatballs.
