God Nightwing is so cute I want to punch him in the face

If you’re judging the viability/acceptability of a romantic relationship between Superman and Wonder Woman before Justice League #12 even comes out, just sit back and think for a minute.
You are judging the work of talented writers and artists who’ve been toward on or towards this, and confining a decades-old company to its previous publishings. Things have changed in continuity before, and even Superman and Lois Lane was not established from the beginning. Give the creators room to breathe and develop their story lines. Then, if you still don’t like it, then you can complain about it. Because then it’ll be about what you’re actually reading rather than your preconceived notions. But for now, none of us know anything yet. Give it a chance.
