Yes, I think it is still nice film. But I think it would be better if it is not about sea-monster hunting, or his lucky moment where he didn't got hurt at all after the incident, or the social think he is a witch where he summons sea-monster to eat his own brother and friends.
And, if this movie want to talk about killing sea-monsters to kill his brother, please show more his effort in killing the monster. It's like magic, and almost instantly saving his brother and others
