Okay, regarding that article, about those suppose racial stereotypes.... that is making something out of nothing. Those two robots are like two siblings, or friends, for example, who are always messing around with each other... The writers certainly didn't decide that they were of any race and neither that they would be representatives of racial stereotypes.
Now, the movie was great. I really enjoyed it. It was worth the money.
OK, dee dee dee. CGI movies suck.
