I agree. Yu Yu Hakusho isn't really even close to being of their most popular series, anyways (in comparison to their highest selling series, like DBZ, One Piece, and FMA). So, I doubt that they would see much profit in getting the rights to re-dub and re-distribute the movie, even though it would be really awesome if they did do that.
Still, compared to the TV series, the movie was pretty average in terms of story and writing, however it was still entertaining, and it would be nice to hear Justin Cook doing Yusuke's voice again, even if its just one more time.
