3) The Flash Is An Awkward Loner
One of the most exciting things about the trailer is that it gives us our first proper look at Ezra Miller as the Flash. With Grant Gustin already playing the Scarlet Speedster to massive acclaim on TV, Miller arguably has the biggest task of all the JL cast as he has to compete with another currently running incarnation.
The DCEU’s take on the character is not so much The CW’s charming leading man and more a socially-awkward yet brilliant loner. A highlight is when he jumps at Batman’s offer to join a metahuman alliance (they need a catchier name). Why? Because he needs some friends.
Many have noted how the scene closely resembles Spider-Man’s introduction in Captain America: Civil War – right down to a superhero billionaire already knowing his secret. This is presumably a coincidence but, even if it isn’t, Spidey’s triumphant debut in the MCU is not a bad point of inspiration.
