Not much violence and gore. Much of it is just suggested. Ghosts with injuries.
The ghosts are not immediately apparent since much of the gruesomeness of modern ghost movies is intentionally not present. When a person is actually revealed to be a ghost, it essentially is done in a sympathetic tone rather than in schlock gore.
A man is shot through the chest. Multiple ghostly characters with blood stains and one missing an arm.
Many people seen lying in a pool of blood; no injuries shown.
Bad guys shoot up a mall but nobody is actually shown getting hit.
