Violence, blood, and murder is frequent.
There's a scene where Fred gets shot on both knees. Moderate but blood is shown.
A character gets his leg sliced off and lots of blood is shown when he applauds. Really bloody.
Velma's mom's eye falls out of her socket, two corpses are shown with their brains removed, a character's leg is cut off, Fred is shot, and other gory images are included. Although, most of the times are intended as comical and heightened.
Blood is frequent and dead bodies are shown. Not too gory, but graphic.
In the best scene, Velma antagonizes a cop who runs her over, and her tooth falls out.
Violence is often played for laughs, but it may be more intense than viewers might expect given the comic tone.
