Well just from that teaser I can already tell that it's more accurate to the books than the film was, as some of the clips were from the Chimera scene at the Gateway Arch, and we have the final fight scene vs Ares on the beach.
Though the guy doesn't have enough biker gear, Ares is supposed to look like a Hell's Angel and his eyes are supposed to be flames. Unless that's supposed to be him under the effect of the mist but then the sword would be a baseball bat so I'm not sure.
The race swapping is really the big element that has me nervous. It's not always a bad thing obviously, Morgan Freeman was great in Shawshank Redemption (where the character was supposed to be a red haired Irishman) but that also wasn't motivated by political agenda so it's gonna depend on WHY they cast this girl.
