'Drunk' OJ Simpson kicked out of Las Vegas hotel

Speaking with Newsday, Roven chose to address fans' concerns, saying that while Justice League will definitely be lighter compared to Batman V Superman, Zack Snyder's latest entry would keep the filmmaker's sensibilities. Batman (Affleck), fearing a threat that could be even more risky than his recent run-in with Doomsday, creates the Justice League with Wonder Woman (Gal Gadot), Cyborg (Ray Fisher), Aquaman (Jason Momoa), and the Flash (Ezra Miller). Of course, DC/WB has also had some major bad backlash from negative reviews of DC Films Universe movies (see: Batman v Superman), and knows that even slight criticsm of their films can start a dumpster fire of fan hate.
