Superb, my friend. Superb.
With a combination of humor, action, catchy music/lyrics, and an overall good aura about it, The Ultimate Showdown has to be one of the best, if not THE best flash movie I've ever taken witness to. I can honestly say that from start to finish, there was a huge grin plastered on my face and at some parts, the grin would turn to sudden bursts of laughter. Truly classic, and epic. Again, one of the best Flash movies to ever grace Newgrounds and my eyes. Keep it up, good sir.
