/rant Admittedly I don't read comics but who/what could be worth "uniting the seven" superheroes for? 7 superheroes really?
Modern villains fucking suck at being villains. Ra's al Ghul's was lame and he got owned and had to have his even weaker daughter do his dirty work. Loki's only popular because he's sexy. Bane was only amusing because of his voice, hardly even a villain. Joker was close but really only had a very short reign of terror against only 1 city. What modern badguy even has a body-count worthy of villain-hood?
Dear superhero movie makers please give us better villains more like Hitler, King Edward the Longshanks, God, El Chapo Guzman, George W. Bush. etc. Less stylish and young, more unhinged evil, more competent.
