I can't allow or forbid you to talk about anything in this thread as long as it's Batman-related, can I? )
Well, I like your view of the Riddler and somewhat share it. To me, personally, the ideal Riddler is very close to BTAS one: very clever, very arrogant. To my mind Riddler should not be tough or have any special fighting skills, since clever people will try to avoid fight up till the last minute. I really liked his portrayal in recent (relatively) comics where he has a certain friendship with me and working like a private detective later, with his own goals. Quite fun. Should you be interested, I'll have a look what comic stories these are.
Well, my tastes depend on the sourse of the material: i.e. inside Batman Returns world I really like Penguin, but hate it when they try to incorporate a monster-version into a "normal world". Same with all kind of series. I hate BBB Joker, but he looks good in the whole world. The same with BTAS most cillains look good there, though Penguin is horribvl in it, untill his brilliant revamp in TNBA. He became an entirely new character, much better, IMHO.
Sorry for that a bit messy answer.
Good day, ladies and gentlemen! )
