You're the one who compared dislike bars, therefore insinuating both situations were identical as if it was somehow evidence against my claim. That's 100% on you. Don't backpedal and try to dump this on me just because you were wrong and then pretend your point and moot example based on pure assumption is valid.
And what you're trying to insinuate with that Birds of Prey remark is complete nonsense. Because even I know you don't believe that. So I don't really get why you said it. Or should I really believe that you think Harley Quinn didn't gain any kind of popularity after Suicide Squad and that you truly believe Birds of Prey flopping has anything to do with Harley Quinn herself? Or are you just so wrapped up in your own argument that you no longer care about what you're saying as long as it can help your point of view?
I'm seeing everything as I saw it back in 2015 when everyone was making fun of him much like they did Sonic last year. I'm talking about the countless comments I read on social media and various news sites, the videos I watched and the discussions I had on forums and with friends and family, for the whole year that it took between Joker's reveal and the film's release. If you have some concrete evidence you want to provide, by all means, show me. I can only speak for what I've seen, but so far, you seem to think that because you caught wind of some hype from several sources, that you're somehow the authority of audience reaction because of dislike bars, thumbnails, and some corny meme made by some fanboy.
I also never said he was universally hated, I said he was widely despised which is completely accurate given the range of outlets I've seen him get trashed on. Yes, he had hype, he had fans, and he still does, but he was still widely hated long before the film's release and no, the audience didn't suddenly have a change of heart over the film's quality or Leto being sidelined either. That's complete speculation on your end, which doesn't even hold up as I've stated before. There's a reason WB canned Leto's Joker film, meanwhile had Harley Quinn booked for all sorts of films, and still went on to make a Joker film without Leto.
