Easily the smoothest and most climactic episode.
This is probably one of your most enjoyable Madness episodes, and by far my favorite of the series. The difference in animation quality and storytelling apart from your earlier work is so exponentially greater.
From the very beginning, it's obvious to tell the atmosphere in the series is becoming darker and more serious. The opening is so epic! It really gives a different approach to starting the action, and leaves an impact on the viewer in such a way that they're left feeling sorry for whoever is in that building. Even as the protagonist shoots and slices through the endless waves of baddies do you feel as though the action will never stop!
Every method of execution by the hero is unique or just plain brutal as well, and leaves the audience with a bloodthirsty craving for more. The ending battle and quirky twist with the clown and Jesus couldn't have been more unexpected, and just seems to mesh well with the normally intense mood. Madness ensues hilarity, after all.
All in all, the episode featured a perfect opening and ending, intense action, exciting music, and much more. The list could go on and on. Krinkels, your work is phenomenal to say the least and will live on forever as some of the best Flash movies to ever exist on the internet. Excellent work!
