He's a fine character. I don't love him, but I don't hate him, either. It's funny, this happened when Jason, Tim, & Damian were created and it won't stop anytime a character is created. People are protective of their pet characters.
For the record I find Tim Drake and Jason Todd extremely boring as characters. You'll never hear me say they need to get rid of them, though. I just don't give a shit that much about ancillary characters (except Dick and Damian).
This is also a loaded poll. No middle ground just "love him" or "hate him"? There should be an option for "like him". "Give him time" is a non answer.
I'll say it here too, whenever I read a scene with Duke in it and I realize it's making some get all upset, I can't help but laugh and think how petty it is.
