It depends on taste. I truly enjoy it. The gameplay is hugely improved from 1 to 2 (so pvp got way better... no more backstabbings when you are still on the other player sholders).
Storywise, I think dark souls 1>3>2... but challenge wise, 2>3>1... But it depends on your style of playing, of course.

Looks like Bloodborn. Are Dark Souls 2 & 3 as good as Darks Souls 1?
