Very true. The DLC is awesome. A couple of the bosses in there are ranked as one of the top 10 in the whole fromsoft collection. One in particular is easily top 3 for me and many others.
Just wanted to add that the DLC is also fucking hard. Like, without spoiling anything from the DLC, the end boss is nuts, the first boss is ridiculously hard and a optional boss is stupid hard. That said, three of the DLC bosses are also some of the best From Software have ever produce and the environments are really diverse and weird. Man, but that difficulty is insane! It makes the end boss of the main game feel like a wimp.
The DLC starts like it looks like From Software went cheap on the DLC and re-hashed content, then it starts hitting you and by the end of the DLC, I found myself nose-deep on Bloodborne related podcasts and forums trying to piece things together. It is great and totally a highlight in From Software's repertoire.
PS: Do not let the difficulty dissuade you from playing it. I was able to obtain all the trophies from both main game & DLC. It was tough but totally worth the ride.
