Although I am not very adept at seeing a poor tomboyish filly being revived and tortured by the psychopathic version of one of my favorite characters in the series, I must admit that this parody made me laugh a lot; maybe it has to do with the fact that I love Robot Chicken.
The only thing I did not like very much was the animation (sorry if I seem a bit demanding) but that's just my personal opinion. But overall it was very nice and funny, good work!
