All I will say is, if that film was the first thing I saw of MLP: FiM...
... I would never have wanted to watch another episode.
This movie is to Pony what "The Last Airbender" was to the "Avatar" cartoon series.
I cannot see anyone who is not a rabid fanboi managing to delude themselves into even believing it to be a passable film. From a film-making standpoint, it's atrocious. From the POV of anyone who loved what FiM brought to children's cartoons, its a betrayal of trust and an abandonment of everything that made the series stand out as something greater than the typical mind-numbing kiddie fare.
I am beyond deeply disappointed. It's disgraceful and a slap in the face to Lauren Faust, who rose above the gilry cliches that this movie embraces and sodomizes itself with.
