Highly creative, which is no surprise coming from Tezuka.
Done in a purposely archaic animation style, complete with cigarette burns, lines, and two frames jammed together on screen simultaneously long before it was cool, the characters interact with these defects in an amusing manner. Tezuka's Disney-inspired animation style works particularly well with what is supposedly an animated Western from 1885.
It's a single idea executed well over 5 minutes, perhaps even overstaying its welcome with a few gags at the end that fell flat.
Overall though, it's a worthwhile, original animation. Recommended to fans of anime looking for something short and unique.
