Assuming he means how in One Piece, you can use Haki to deflect stuff.
I don't hate it, but I actually kind of prefer when Jiren kind of just acts that is all one big bore, a job that needs to be completed, rather than stuff like him putting down Hit's profession and what not. Obviously though it's not like this is something new when considering last week's episode where the best thing he could say concerning Goku is that Saiyans are interesting, as well as him doing his cocky pose after beating Kale, allowing Goku to set up his Spirit Bomb, etc. That's clearly just his character.
