It's not an accomplishment, but it's definitely more, as parent commenter said, "performative" than saying they read any popular author of today.
As you yourself pointed, Dostoyevski is a required reading in high school and as anybody who had the "pleasure" of attending school, knows required reading usually isn't something what appeals to the youth (killing joy from this activity is another problem).
That's true of a lot of students, but not everyone! A couple of classmates in particular come to mind who definitely, genuinely loved the books we were assigned.
Heck, while I didn't like most of the books we read, there were a handful I loved! Montana, 1948, for example, was amazing.
Admittedly, the reader effort is still ridiculously far below that of the author.
Quoting Fry: "It took an hour to write, I thought it would take an hour to read"
Murrow isn't strictly a performance arts school, and it's not located in a particularly hip or excessively wealthy part of Brooklyn.
>I am glad to see "the kids" continuing to question & challenge
They are the children of (rich?) Brooklyn hipster parents at a Performance arts school[0]. Who exactly are they challenging? If anything, they are being congradulated and pushed along on the hipster path. There are Brooklyn hipsters who unironically use 1980's antenta phones. If anything this is a worn out trope.
