Nope he is an auteur.
Trillion dollar studios kneel in the presense of those true artist.
If they completely ignore the events of MoS, BvS, Suicide Squad and the Justice League and have no cameos by Superman, Wonder Woman, Flash, Cyborg, Steppenwolf, Luthor, Lois Lane, etc and just focus on the Affleck Batman's Gotham, it should be fine.
Fat chance though, Deathstroke is in Justice League.
Well since this is supposed to take place well before the world was introduced to The Superman, that might be the case.
Can't say I'm a fan of Matt Reeves. I've see the Apes films and they're ok, but not very memorable.
I'm sure he'll make the film WB wants him to make.
To be fair to MR the Russo's also came out of nowhere and now they're the gods of superhero action.
