This is a special kind of movie, since it's being so many different things all at once. It's a type of movie that feels more like an old fashioned Japanese samurai movie, even though this movie is being a Taiwanese production.
What I especially like about it is that it starts off as something totally different but eventually ends as am adventurous movie, with lots of material arts fights in it. It's a long movie (about 3 hours) so it takes its time to slowly set things up and let stuff develop into something different. This ensures that the movie is always slowly but gradually developing and also never stands still, so there is never being an actual slow moment in this movie.
As the story develops, things also definitely get more interesting and fun to watch. The movie turns into a real adventure, in which the main characters are almost constantly traveling and having encounters with people that want to take their lives. This ensures that there is also plenty of action to enjoy in this movie, involving sword fights but also plenty of hand-to-hand combat, with every now and then Wire Fu effects involved.
It's also being a real innovative and original movie at times with some of its editing and camera techniques. In that regard this is also being a real '70's flick, a period in which a lot of experimenting with editing and cinematography was going on. Especially the cinematography is great at times and also does a good job at capturing the right mood and brining the environments very lively to the screen.
It's just the sort of movie not an awful lot is being wrong with. It does everything well and within its genre it's being a great watch!
