I actually really doubt they'll ever become that explicit with it anytime soon given how closed off this version of Batman is described as being, but I disagree with you there. I'm more than fine with those people being unhappy, especially when they'll inevitably have to admit the show is actually good once they watch it any way (and they'll all 100% watch)"Bruce Timm's weird obsession with Bruce/Babs making its way into this show too"
Oh please not this tired discourse again.
I just know that no matter how well it's done in Caped Crusader or how different their versions of the characters are, a large number of overly loud "fans" who probably won't even bother to watch the series will yell all over social media "oh Bruce Timm is shipping Bruce with Barbara again, clutch your pearls!" and take a lot of attention from what appears to be a really good show.
The poster does say that there is "nothing explicit" shown, so I'm hoping she's just seeing things when they're not there, and save us all the trouble.
