Disclaimer: I love DS3. I have about 300 hours in it and I think it's magnificent.
Having said that, I'm not sure I agree with the quoted part. It does contain some elements of the best of BB and DS but at some points it misses what makes either of those games great. Bloodborne's great strength is that it's a completely new, unique world, absolutely dripping with atmosphere. It's fast-paced, and both the gun parrying and the rally mechanic really help with an aggressive, on-the-move playstyle. The whole things just fits together.
In DS3, it often feels like the enemies are at Bloodborne speed but your character is stuck at a Dark Souls pace. You can't be as aggressive as in Bloodborne but nor it is as measured as Dark Souls (and Demon's Souls). Parrying, in my opinion, is the least satisfying (and outside of certain boss fights, the hardest to pull off) in this one. And let's face it: it's the third game in the series and didn't really bring anything that we hadn't seen before. It goes in on the fan service a tad too hard at times. There's little that is really original about it - and because of that I understand why someone might absolutely love Bloodborne and be indifferent towards DS3. At one point you can get sick of cathedrals, after all.
Where it really shines, in my opinion, are three things:
- The bossfights: the best in the series apart from the Old Hunters DLC. Abyss Watchers, Twin Princes, Slave Knight Gael, Dancer of the Boreal Valley - brilliant fights (and these are, at least, mostly original and creative).
- The music. Obviously highly subjective, but it's my opinion.
- The best PC port of the three. Beautiful (well, for a 2016 game), runs well, stable, has some absolutely filthy hitbox porn.
