I hear you - but I get why they did it. The slang is thrown in to do some of the heavy lifting when the accents aren't as strong as they could be.
shyt's a delicate balance - I've been writing something which needs a bunch of slang in it - if you put in too much, 'civilians' won't get it. Too little and you risk losing authenticity.
Real talk - they owe Cheo Coker big time for this.
There was no way I was coming back for Iron Fist Season 2 with Scott Buck's characterization of Danny as the foundation.
Instead of Defenders - I'd happily take a 'Heroes For Hire' show anchored by Luke, Danny, Misty and Colleen, with cameos from Daredevil, Jessica and The Punisher.
