Several scenes of the damned -- all men, for some reason? -- being tortured in Hell, but it's mostly implied by sounds or the motions of whips, cudgels, etc. There is one view of cut-off tongues in a bowl for a few seconds.
Four incidents of "real-world" violence -- but with demonic strength -- including murders, dismemberment, a dog eating a human organ. Considerable blood is seen, but the impact is lessened by dark lighting and a somewhat unreal mood.
