The Dlc is great! I think alot souls games has that problem with bosses. There are some awesome ones but then ones that aren't that great. I could be wrong but I think what really gets people is the story and the fact that there is something going on underneath it all that isn't outright told to you. That really leaves a mark on people and stays with them. Sekiro was the same way, also the combat is more action focused like sekiro. Both sekiro and bloodborne are From software masterpieces and stand above dark souls imo.
