Let me save you all the trouble for reading/watching reviews for the new AC, I'll summarize:
The new Assassins Creed game is, indeed, an Assassin's Creed game.
That is to say, of all the Assassin's Creed games ever made, this is certainly one of them.
Ok you want a little more? Well some of the pre-release criticisms revolved around having two protagonists and the worry from some that they couldn't play as a the big warrior guy the whole time, and others worrying that you couldn't just play as the sneaky ninja chick the whole time. Now that the game is out and it turns out you can mostly play as whomever you like, there are complaints that the game was designed to allow you to play as whomever you like.
Ok in case anyone else had any actual interest in the game other than using it to shit on AC, Ubisoft, open worlds games, wokes, the AAA game industry, or whatever- apparently it actually runs pretty decent on PC, which was the only actual worry I had.
