I think my main issue with Robot Chicken is basically the same one that I have with Family Guy; just mentioning or showing things from the 80's, even if you throw in a little heavy-handed parody, isn't funny in itself- mostly it comes off as lazy writing. The two second ones can sometimes be interesting or funny, but the long ones tend to go on far too long, and a lot of the time it seems that they ran out of ideas before they wrote the end. I think it's a really good concept overall, but I keep hoping that they'll make some that live up to their potential. Maybe the new season will be a more finished product.
