I wish people weren't so fooled by their ego to point the finger with obvious fallacies in their Logic. If you are going to review episodes of this series than at least understand that 90% of the stories are based on stories from SF Writers(To me the best thing about the series) and this story is no different and understanding this means understanding that they did copy a story alright, but it was from the writer who they paid to turn their story into a visual representation, and guess what, That story was written before the Simpsons did it(so ipso facto, It's the Simpsons who would have been doing the Ripping Off and not vice versa)
Anyway it's a OK episode, nothing great, but entertaining enough to keep you watching until the end(only ten minutes) oh when I say till the end, obviously you guys watch it on netflix and most people will click or just wait the few seconds where it just auto skips the end credits, Well Obviously those are needed in this scenario, in fact I think it's a shame they didn't notate the original source in the beginning of each episodes especially knowing how most Netflickers skip them automatically.
