I don't understand why a great actor like Chen Kun participated in this film. This is for kids. Maybe that's his goal, he feels like a father, leading by example, fighting "evil". The premise that monsters are equated to evil and then he is supposedly unbiased, only on the grounds that he is half-monster is childish. I don't care about the production, because visual effects are again, appealing to video game addicts, which I'm not. I watched reluctantly less than half of the movie, waiting for a turn of events. But it is so predictable, following all the cliches, so I dropped it.
