I saw this today with my summer-camp group. I enjoyed it well enough. More than I remember enjoying the first. (I have not seen the second.) It is a genial-if-disposable children's film buoyed by Genndy Tartakovsky's rather incredible visual imagination and acumen. It is quite beautiful on a purely aesthetic level. And the gags come so fast and furious, it almost ceases to matter if one lands with a thud because another is right behind it.
