I admit I have a thing for Aslan. It started when I was a kid and saw the cartoon version of The Lion, the Witch and the Wardrobe movie. (recently purchased off ebay) Then I grew up and understood the references to him being a version of Christ. Being Christian myself I liked the link. (Not one of those holier than thou Christians, sorry about them.) I even found this beautiful pic online of some original artwork by Ryan McGrath of Aslan I think would make a great tattoo. It was an entry for a poster contest for the newer movie, which I also love.
