I honestly think Narnia doesn’t work that well as a Christian series in that Aslan’s hardly as humble as Jesus was (even DC’s Clark Kent does the same or similar), another problem’s that whilst Aslan makes people come to his world, Jesus and Superman do the opposite and save others. Jesus saves a lot more, Aslan only saves a few.
To the point where Aslan might actually be an Antichrist character: grandiose instead of grounded, arrogant instead of humble which’s what I feel about Aslan and why he never struck me as a convincing Christ figure. I swear, even Superman does some of the things Aslan doesn’t like bothering to save and defend many more.
Trying to be patient with others like Supergirl and Superboy (if I recall), whereas Aslan’s more often than not aloof and stern. I actually think Narnia speaks to Carnal Christians in that the Christ figure needn’t to be humble and grounded when he could be grandiose and haughty. Why bother being a normal person for long when he could still be a lion?
Aslan hardly ever shows the same dedication to be humble and inconspicuous the way Superman and Jesus do, Jesus might be the king but he’s content to ride on a donkey and be working class whereas Aslan lives in a palace. Even Superman’s humbler than him, willingly living as Clark Kent the reporter.
I guess the real problem with Aslan as a Christ figure’s that he’s way too arrogant and proud to pull off true Christlike humility to appear as one of us rather than the aloof, growling creature he really is.
