It was super easy. So far the bosses have been easy AF the only one I have died to is the First boss, and that was because my controller cable broke. Everything after that no issues. DS2 was harder.
I know I'm not the first person to say it, but the bosses don't feel challenging at all compared to the normal enemies in the game. Sure, they have a bit more health, but they don't really attack at 120mph and are fairly easy to deal with. The first game was the other way around (mostly).
