I dug this film, it's got that late 70s to very early 80s vibe. It's a fresh indie take on the gangster genre, a story told from the perspective of a character who usually doesn't get much attention. It's a slow noir-ish burn, which might not be for everyone. Personally, I appreciated the suspense of seeing the story from the protagonist's limited perspective and struggles. Ultimately the story, like all good gangster films, ramps up to an exciting and satisfying resolution.
I thought Rachel Brosnahan and Arinze Kene were excellent portraying people reluctantly doing their best in a desperate situation. Pardon the pun, but after years of Mrs. Maisel it was marvelous to see Brosnahan flex her dramatic-thriller skills, this character reminded me of her role in House of Cards. As I mentioned, this film has a good sense of period and style, but it's tastefully subtle, competently shot and edited with a sense of control. Being born in the 70's, for me the art direction really stood out, it's immersive in its attention to detail without relying on heavy handed cliches like so many films do.
Ignore the 1 star reviews, when they're this early they're typically motivated by an agenda. Or they're written by immature viewers lashing out every time they don't find the spectacle they're conditioned on.
