If you love the ever burgeoning list of computer animated flicks, it's worth seeing "Robots" just for the superb visual design. In fact, that's the only reason to see it.
This is a "schtick" movie, like the classic Warner Brothers cartoons of the 40's & 50's. I can handle that for 3 or 4 minutes, but not for the 91 minute running time of this movie. The folks at Blue Sky have failed to learn what Pixar has always known: Story. Story. Story.
"Robots" treats us to a pastiche of set pieces stuck together by a plot that is so clichéd it's virtually impossible to put a spoiler in here because you've already seen it all before: Evil corporation, valiant naive hero, funny sidekick, "you're okay just as you are" theme. And it's really too bad because "Robots" is a visual treat. The gleaming surfaces and rounded designs remind me nostalgically of my parents 1955 Chevy Bel Air. But even there it doesn't always make sense. Whether something is a robot or not depends not on the story, but on whether they can get a joke out of it.
See it for the visuals. Skip it for the story. It's one of those "near miss"" movies that will frustrate you, because it could have been great.
