What is wrong with this episode is that every jab it makes at contemporary society, every "satire" (if you can call it that) is too obvious for rebuttal. They reduce all points ab absurdum and make it seem like the gay-marriage issue was simply a matter religious bigotry against tolerance. And if you think gay marriage was or is still a controversy solely due to homophobia, get real. Homophobia is a relic of long ago and like racism and sexism is as taboo as anything else. In fact, anybody who still is homophobic is probably more likely to be targeted for abuse (talk about hyper-correction).
This is the worst episode of season 6 and definitely of the bottom tier when it comes to all Futurama episodes. Terrible job at the script, characterization. And to think that most critics reviewed this episode favorably. If you can stretch a social issue ab absurdum and pass it off as satire, monkeys will be pleased. This isn't high art, but I expect some actual comedy of which this episode had none. Season 6 was overall a decent start but it'll never again be like the golden years (seasons 1-3). This episode, like a few others, is a prognosis of the deterioration of quality that all shows undergo. It happened with Family Guy with its renaissance and it'll happen here.
After the previous disappointing episode this is a real return to form. The story was good with plenty of great jokes as well as an enjoyable guest appearance from George Takei as his own preserved head. The story of the 31st century's attitude towards robosexuality is clearly, and not too subtly, a reference to the 21st century's changing attitudes regarding homosexuality. While some may find this a bit heavy handed as it is quite clear which side we are meant to be on I wasn't bothered as it managed to stay funny even while it was being a bit preachy. As the episode progressed I thought that the character dynamic would be left changed at the end but ultimately things returned to the way they were in a way that didn't require anybody to act out of character. Overall a good episode.
In this episode, Amy and Kif break up and after that, Amy starts hooking up with Bender. Once everyone finds out, they're shocked. Professor Farnsworth and a lot of the crew don't approve of the human/robot relationship, as do many of the population. This leads to a big controversy and everyone voting whether it should be allowed or not.
Overall, I give this episode a 7 out of 10, which in my ratings book is: Great.
