I seriously don't. It was really bad. the fight scene were garbage, the demon costumes were ridiculous but them fighting was even worse than the silly scenes of the sects fighting. The storyline made no sense and in no way came together well. The funniest things were Seven and the monkey.
But I liked it. Right as soon as I realized that everything was not going to be good, I let myself just enjoy the acting. Most of the characters were great and the acting of bad scenes was good.
Maybe if it was a short series instead of a movie, thing would have been better. They could have built the world and characters better. But instead they squeezed it into a movie.
Oh, well.
