This movie wasn't good at all to be honest.
The beginning was promising with the mountain climb and fall but all the movie was centered around the chase of the gem and I didn't like that at all, even the fight against that majin was lame.
Pretty interesting to see this movie, too bad that the fansubs haven't covered the original series up to where this part is supposed to be (only up to ep 77 of 243 at the time of writing this comment)
