The original had a cast of interesting voice actors, like Adam Samberg, Cheryl Hines and Jeff Daniels. I didn’t see it, either. I had to look it up. This sequel is one of those dirt-cheap, cynical affairs that aims low and falls even lower. It tries so hard to be fun and quirky, but without a solid narrative structure or real dilemmas for its paper-thin characters, there’s nothing at all going on here.
Unless you count Kilowatt, the alien character retrieved by our protagonist, Comet, in a huge out and back journey that has exactly nothing to do with the central conflict. Kilowatt is a victim of what I call “forced-cute” design. He (she?) might have seemed cute in theory, but without the raw talent necessary to pull off that kind of design, he just looks like an engorged tick.
