There is a very lengthy fight scene toward the end of the film, but it's not too brutal, and no one is really hurt.
The main character is being chased by the dogs through the garden maze. The scene is rather comedic scene.
We see the skeleton remains of the ship crew. Not disturbing though.
The pirates are being attacked by the horde of bees. It is done somewhat hilarious/comical for some viewers.
The four men (seen in silhouette) being beaten to death by unseen assailants. Later, the pictures of each dead men are seen. Brief but it is disturbing.
The three teenagers are being attacked by unseen assailants. Later, we hear that the three are missing and we never seen again. This may be upsetting.
