There's too many and a perfect amount of things to love about it. So instead here are a few I believe could have been better:

• Everything off the loading screens would have been a lot more impactful first experienced during gameplay, not as a still image in-between deaths/travel.
  
• Compared with the way it's handled with the Bonfires and Sculptor's Idols, the simple fade to black at the Grace sites comes across as too much of an omission.
  
• The ever-present music is a little overbearing at times.
  
• Personally, not a fan of the bombastic musical piece in the main menu. It's great, but an odd choice for the start of the game. Even when launching it for the hundredths time, I would much rather skip it as soon as possible, mostly because it just doesn't fit with whatever follows right after, most of the time.
  
• The opening slideshow is underwhelming. Not that the rest of the experience is in any way lessened because of it, but it clearly tries building excitement.
  
• With what it allows the enemies, the game expects a lot from the player. How much of an issue it is, heavily depends on the way one chooses to play it however.
  
• This is the smallest slightest quibble, but still. Smithing stones 1 through 9? Gone are the days of titanite stones, slabs, shards, chunks?Godefroy very narrowly avoided getting named Godrick 2.

none of these and not all of them together make the game any less than absolutely wholly perfectly enchanting. There are no words to describe how wonderful it is if you let yourself be lost in it.
