The star of Breath of the Wild's DLC isn't the all new content - it's hard mode
Master mode is, well, masterful.
If I'm honest, I wasn't really very excited for this first The Legend of Zelda: Breath of the Wild DLC. Part one of the expansion pass always looked like the boring part: while part two would contain a story expansion to the events of Breath of the Wild and based on the teaser might even see you play as other characters, part one simply featured additions to the base game.
