Not the best I've seen.
Animation: Excellent. Choreography: Great.
But not only did Boomerang have a SEVERE advantage over Mr. Kickman (who's kicks just seemed average to me) but their fighting styles just didn't define them. I felt as though Mr. Kickman was trying to do too many kicks, simply because his kicks were the only thing in his arsenal. It would be one thing if his kicks sent boomerang through the wall, or at least dazed him on impact, but instead they just fall flat. You need more impact on both sides. I think Boomerang would be in for a rough fight if he was fighting Steel Stick, or something similar, and if Kickman's kicks actually had noticeable impact, but instead what we're left with is two stick figures, one with a boomerang, fighting in a sewer.
