Red Hood by Mark S. Miller. The animated movie was good, if this is the same Red Hood (Robin) as in the film. I hated in the film where he refers to his weapon as an AK47. 9 out of 10 people wouldn't know what that was. Your grandmother could own an AK47 with the right permit.
Jensen's speech in this scene. Tell me if that ain't Dean Winchester after Sam didn't get him out of Purgatory. Batman Under The Red Hood. Also makes you think about when Dean said "I'm Batman." Chills.
