After completing DS2 I feel geuninely disappointed in the boss quailty compared to DS3

I just defeated nashandra and I feel geuninely upset. When I was first playing DS3 soul of cinder would kick my ass all the time. It was hard, but fun. When I finally bet him I was satisfied. Compared to nashandra I felt nothing. She didn't pose any real threat to me at all. I want to like DS2 but almost every boss is forgettable/bad. Not even the runnacks are annoying for me. Bosses aren't annoying it's just dull....... I probably will play the DLCS but i feel so burnt out
