I'd say anyone who's a ব্যাটম্যান অনুরাগী would প্রণয় all অথবা at least most of the characters Gotham City has to offer, and ব্যাটম্যান অথবা the Joker don't have to be your favorites. Still I'd have to say ব্যাটম্যান would be the favorite. For obvious reasons.
I think mostly everyone like ব্যাটম্যান & The Joker,
ব্যাটম্যান is mostly liked because he's one of the superheroes without any powers (spiderwebs,supervision,invisible technique etc.) he just trains, got great idea of a serious situation and unique weapons also he doesn't kill the villains in the end.
Joker is mostly liked, maybe it's because he's funny (in a good way) he's mad, got great ideas how to defeat ব্যাটম্যান without him thinking, and আপনি can't even judge him দ্বারা his personality and his image of a villain.
These are my opinions of why most অনুরাগী of Dc/superheroes/Batman like The Joker & ব্যাটম্যান
I don't think I've ever seen ব্যাটম্যান himself receive hate except from people who aren't really a অনুরাগী of the franchise. I don't know if they count. XD
The Joker seems to be the most liked villain. I've seen very few people dislike him.
Kind of on the fence about Alfred. I agree that he doesn't seem to be disliked দ্বারা anyone, but on the other hand, I'm not convinced he's all that জনপ্রিয় either. So I guess that depends on what the প্রশ্ন is - not sure if everyone particularly likes him, but he certainly doesn't seem hated!
Regarding Harley Quinn... I've known some to dislike certain versions of her. So she's another character I'm a bit iffy about when it comes to hate. That said, some incarnations of her are very popular!
As for Robin... well I প্রণয় him, but I'll admit I have known him to receive a considerable amount of hate from some people. So I don't think he's the character that's hated the least, but fortunately there are still people out there who like him!
Something I've noticed within the ব্যাটম্যান fandom is that আপনি don't get too much of অনুরাগী accusing characters of being "overrated" অথবা whatever. There's so much of that going on in আরো fandoms than I care to think about, and honestly, that word gets thrown around so much it হারিয়ে গেছে all meaning long ago. But luckily, ব্যাটম্যান অনুরাগী for the most part don't act like characters are overrated just because they don't like them but someone else does. Plus, what probably helps is that I've seen people justify their reasons for liking/disliking characters too, which is cool.
So yeah. শ্রদ্ধার্ঘ্য to you, ব্যাটম্যান fans, for being awesome like that. ^^
