Psychological Depth in The LotR Movies: An Essay.

Faramir has obvious anger-issues. Seeing the way his father treated him, especially compared to his older brother, it is obvious that his father's rejection has instilled a lot of repressed anger and an inferiority complex in him. This explains why he kidnaps the Hobbits, as he feels their physcical smallness makes up for his self-esteem's smallness, and then why he ALWAYS has to pummel Gollum, as Gollum's marked physical differences to everyone else present allows Faramir at long last to have a target to pick on which is more vulnerable than he.

Now Denethor is not only a dealer of domestic abuse, but a victim. Gandalf's constant beating result in thoguhts of suicide...which would have been averted, had not Gandalf got Shadowfax to kill him after Denethor realises that death is not the answer.

Gandalf is Morgoth returned.
