Never said it was a win, said it wasn't a complete misfire. Complete would be Catwoman or last Fantastic Four level bad. There are mediocre movies, bad movies, and total crap movies. Mos isn't that bad, made profit, has fans even now, so while you can dislike it and blame it for Superman's state of affairs now, it isn't fair to call it a "complete" misfire. We've seen those before, let's pray a Superman movie never quite makes it that low. So misfire maybe, complete misfire no.
And still, arguably better in my opinion than cameo guest star at best status, which we have now going forward. Unless you really, really love Cavill and think snippets of him without Snyder is just a glorious thing, the future ain't bright.
