Yup, I mean Finn Jones. I had to double check as well, but apparently every season of all of the Netflix shows have had the same casting directors. But of course I have no doubt the showrunners for each show have a big influence on who they cast, so I can't put the blame for that particular slip-up only on the casting directors shoulders. Scott Buck is just as much to blame there, if not even more so than the casting directors.
But yeah, casting for Daredevil, specifically, has been perfect since day one. That includes Bernthal as Frank Castle. Right down to the likes of side characters such as Wesley, Leland Owsley, Vanessa and even Turk. All of them are great actors and perfect for their parts. There isn't a single bad egg in the basket. I know a lot of people might disagree, but even Elodie Yung as Elektra was perfect casting to me. I mean, c'mon, SCOTT GLENN as STICK! To me, that was on par with casting D'Onofrio as Fisk in the camp of "actors that were born to play this character".
