As you can probably tell, I'm kind of a fan....
Really excited to see him on the big screen finally, I hope The Rock will do him justice. My hope is the Shazam movie will make him a household name, many comic book fans know the name but not so much the general public. He is already one of DC's and comics in general, greatest I'll say "not-heroes" since he blurs the line between anti-hero and villain somewhat, but I really think he could go to that next level, having his name mentioned up along sides the Jokers and Magnetos of the world.

In general I've been pretty satisfied with his portrayal in the New 52, however I felt he went down way too easily against Ultraman during Forever Evil, though he did kinda get his revenge.
Also during FE I liked how they kind of hinted at a friendship or at least mutual respect between him and Sinestro, I could see them getting along, they are both motivated by wanting to protect their people and both are not afraid of using extreme force to do so.
