I've never heard of this woman whatsoever until I started watching trailer reactions a few days ago. Apparently they've only done one other movie, like someone else mentioned above me. If there's anyone talking up the director, it's probably Twitter types pushing the fact she's a female minority (Asian-American) director. They damn sure don't have much any a body of work.
(Unless you mean the John Wick director, who IIRC is not here. They got the fight choreographer from John Wick to help with fight sequences in this film, not the director themselves)
Anyway I'm torn on watching this. The supporting girl cast just seems like they're there for a paycheck, doing the bare minimum. The main villain seems like they're into the part though. I don't read the comics, so I don't know much about any LGBT agenda stuff or whatever. I don't have any issue with BM being gay, but I can understand why fans of the comic might if it's not in line with accuracy to his portrayal in the comic series.
I'm still trying to figure out how that Grace chick from Beyond The Trailer compared this to True Romance, though. I didn't get much of a True Romance vibe from the trailer, but I can see some trace similarities. Now they've got me picturing Patricia Arquette's character somehow driving off to Gotham and going Harley Quinn. Damn cinematic universe crap xD.
