I can't say the movie was bad, but it wasn't not good either. The fighting scenes could be better if not for the fast-forward effect which was used all the time when there was a fight.
Some facts about the movie: the main character Wendy is not Chinese, she is Thai; most of the Chinese characters in the movie were played by Japanese.
I think they didn't use a good opportunity for a joke or a funny scene by not showing us what would Wendy's mom say when she saw that all her items for the exhibit were destroyed.
Now some bloopers. Peter was possessed by the evil spirit and his hair was messy after taking off a motorcycle helmet, but when he entered the house his hair became well combed even it was shown to us how he was walking and entering the house and we didn't see him combing his hair.
Wendy's friend is falling in the water in the prone position, but then next shot she is in the supine position.
Jessica is replaced by a Japanese stuntman and it's so obvious -
