Zack Snyder has produced DCEU films that had massive potential, but ended up with poor results. Both Man of Steel and Batman v Superman have rotten on rotten tomatoes. In the 2nd week at the box office, Batman v Superman dropped 68%, even lower than Batman & Robin which dropped 63% at the box office in its 2nd week. This means more people came back to see Batman & Robin than Batman v Superman. Snyder is just not a good storyteller. He doesn't understand complex characters like Batman and Superman. He simply can't be trusted with the most important films in the franchise like the Justice League with his track record right now. If we believe there is even a 1% chance that Snyder will screw up another DCEU film, we have to take it as an absolute certainty. Warner Bros. must fire Zack Snyder and replace him with a more qualified visionary (e.g. Christopher Nolan) in order for the DCEU to reach its full potential.
