If you are a fan of DC Comics, this is a good movie. Not awesome, but Good; you'd like it. If you are not a fan of DC Comics, don't waste your money.
My favorite line was Rorschach. He was in prison for killing someone. At least 50 of the other inmates had been sentenced to prison because of his efforts and wanted retribution.
One day they were in a service line for a meal and this large black man had a shiv, talking smack to Rorschach. The big man went to stab Rorschach and he used his metal tray to block the attack and then some Judo moves and had him on the floor. Then he reached for a vat of boiling grease that was conveniently located on the service line and splashed it into the large man's face.
Rorschach turned to the group of inmates in the mess hall who were all watching the action. Rorschach said, "See, you all though I was locked up in here with you. But really, You're all locked up in here me!" Implying that they should be looking over their shoulders for him rather than looking to him to revenge.
