That was not what I expected to see. The music and voice-acting were really nice. The joke itself was very good, it seemed like something out of The Venture Bros. I really loved the way The Mastermind turned out to be a childish idiot throwing lame insults at his reasonable henchman. The ending was nice as well. The style was awesome, with its color palette and badassness. The only flaw was that a couple of lines sounded a tad unintelligible and the "this blows" line seemed like it came from the tits.
Overall a pretty simple short, but it had a very good punchline and had quite a bit of graphical and voice-acting talent.
