Just let yourself be entertained. Imagination, creativity, homage, recycling, all together to give us an immense enjoyment. With or without references, it is an appreciable work. Warning: It can cause an irresistible urge to purchase katanas, retro trainers, classic cars, take kung fu classes, take Japanese classes, watch anime, give a scratch to a pimp, sell the trailer and hug your kids to the sound of a Morriconian sundown.
