Rule number one: don't make it a japanese folkore based movie if you don't knox your basic japanese history and your actors can't pronounce the two most used japaneser words in the story. "Shogun" pronounced as "Show Gun" and "chikara (power) pronounced "shikara" (an asian cousin of Shakira maybe?).
The rest of the movie is a train wreck and despite Nemic having been part of more crappy SyFy movies than you can shake a cattle prod at, none was as lkame as this one. He should have stayed away, he was the only decent bit in it.
