I mean, DC is nearly incapable of making a good movie, regardless of which comic they are drawing from, so not sure why anyone is surprised here.
Wonder Woman was probably the best they've done, and even that was like still a B- sort of affair?
Holy shit though you fags need to calm the fuck down about this movie though. You're just as pathetic as all the random nobody blue checkmarks you trawl up from the depths of Twitter, just so you can sit and wank yourselves off about "lol the movie is only mediocre, take that feminism" or whatever the fuck it is you seem to care so much about.
