Animation is well done,
voice fits perfectly for the intended effect,
creative,
felt a bit too long (but I don't know the song that it was a parody of.)
Being a brony, I figured (or some other people figured) that I would likely be offended by something that has a preview picture like that on the frontpage. Quite the opposite, actually. The nice animation and voice acting worked well in this context, points I can't argue against. I liked it for being something I perceive as a funny criticism to current, silly, hating trends (reinforced by the links provided after the video.) Something about satire I guess, but I can't really assume that it wasn't hating bronies and otakus or not.
Either way, good work deserves its praise. As far as opinions go, I was smiling for the majority of it.
