I can't say that I don't believe it though. The announcement of a Joker film outside the DCEU actually gives me more reason to think that a Batman film that stands alone is something they're considering. It's like they don't have a clear direction for what they're doing and frankly I don't think they ever have.
I just can't give WB/DC any goodwill to think they're not somehow screwing things up. The manner in which they've handled the DCEU so far is such a sloppy, convoluted mess and it's ridiculous. It shouldn't be this hard but it's like they're making the dumbest decisions over and over. Eventually the DCEU is just going to fizzle out completely I feel like because there doesn't seem to be a clear direction for it. They're constantly making announcements and yet no progress seems to be happening on most of them. The films they've made thus far really haven't been that great, even Wonder Woman while better in comparison to what came before it is an average film for the superhero genre and I feel has been somewhat overrated by fans who wanted a good film and latched on hard to the first decent one. The universe building they've done so far hasn't been very well done and major characters are being handled in ways that most agree aren't the best.
There just seems to be new drama every few weeks with one of their projects and I can't just sit back and ignore it. There's clearly a problem behind the scenes and it doesn't seem to matter what talent they throw behind what they're making (there are a bunch of great actors and directors on these films) because without a sense of what it is they're actually doing things are going to continue to just flounder. It's honestly amazing how badly it seems like they've screwed things up.
I'm sure fans are going to rush to call me a DC hater or a Marvel fanboy but neither are true. I just continue to be utterly confused and frustrated with how these characters are being handled so poorly.
Everyone has their own opinion of course but I'd have to disagree on Wonder Woman. For me it is my favourite super hero movie since The Dark Knight. Judging by the favourable reviews and great box office I'm not alone in that.
