I like the idea of Riddler being the ultimate Beta male villain, hiding behind a screen like Oz. Especially since the movies mostly had alphas (Joker, Bane, Ra's, even Harvey) The hacker thing always made sense to me since I imagine him throwing up his riddles on computer screens, phones, and billboards.
I feel you guys though, especially since currently in the comics Riddler has been shown as an extreme threat that challenges Bats the most intellectually.
But thanks for the kind words about the piece. Glad you guys mostly like it. Gonna do a Clayface solo next. I'll just post it here later.
