I also have no clue about DC but it appears that the new team has learned nothing from the old team and instead of building up to a team up movie slowly introducing characters in their own solo movies as Marvel has so clearly demonstrated is the one and only way to make successful cinematic universes they are doubling down on the first movie featuring fucking everyone with no introduction explanation or buildup of these people, it will get shit on completely like all previous attempts at making trash DC universes.
What I really don't get is why they are rushing once again? MCU is dead as fuck everything after phase IV has been trash with the only decent films being a nostalgia-fest spiderman and upcoming Fox crossover Deadpool & Wolverine. MCU and superhero films in general will not recover for years, now is the time to start right and lay the frame work. Start with 1 fucking superman movie, 1 fucking batman movie, have them cameo in each other's films in the post credit scene to show you are building up to a single universe. This shit isn't fucking hard it's paint by numbers at this point why are you fucking it up?
Look Gunn is ok at doing the weird kooky team movies but both instances he was introducing teams into well established universes (GotG and suicide squad). this looks like a fucking disaster, would rather watch a kevin smith rendition of superman arguing with lois lane on how many dicks she has sucked then this.
