None whatsoever.

People are tossed about and hit by debris.

A car is lasered in half during a high-speed chase sequence.

A character's mother is fatally stabbed.

A character has some small cuts after a battle.

A digital program loses a leg. We can see the amputation with several red cubes in a few frames, until he, along with several other programs, are destroyed by an explosion, that disintegrates them. For some viewers it can be a bit graphic, even though these are programs without flesh and blood.

Shit and whore are using sparingly alongside lesser profanity.

Alcohol reference.

A character is dying of cancer, which could be upsetting to sensitive viewers.
