Pros:
It's 8th gen Dark Souls. Great bosses, fantastic level and creature design, co-op and pvp blended seamlessly with a single player story and lore and backstory you can piece together from details in the world around you. It's a challenging series but always balanced and all kinds of playstyles are viable. The series still has my favourite swordplay in videogaming and the sheer variety of weapons each with unique movesets makes almost every other RPG look bad (and that's before you get into the variety of shields, armour, rings, consumables, miracles, pyromancies and sorceries).

Cons:
It still falls short of the original in most of the same ways Dark Souls II did. My main gripe is that it doesn't have the intertwining world of branching passages and shortcuts that the first Dark Souls had and being able to warp between bonfires from the very beginning takes away from exploration. They also nonsensically repeated Dark Souls II and Bloodborne's most annoying flaw and made you go through two loading screens every time you want to level up rather than just letting you do it at any bonfire.
