To get revenge, the mermaids hatch a plan to kill Liu.
But of course, Shan and Liu begin to actually fall for each other, complicating the plan.
But when the farcical elements fade away toward the end, the movie becomes far less enjoyable.
The climactic scene is a blood-drenched massacre that feels entirely disconnected from the movie up to that point.
And after that, the film shifts into a dramatic romance for one scene between Liu and Shan.
Another thing that suffers from the endings shift away from farce is the effects.
However, the water effects created by the elder mermaid do remain breath-taking throughout.
