Almost everything about it ?.
It looks pretty but the controls are terrible. Everything feels so slow and clunky, it almost feels like a chore to do anything. The combat is poor, the missions are really repetitive, sometimes it feels like Arthur is fighting your input.
I'm finding it a real struggle to continue playing.
Edit: Just to add I'm playing it on a Series X not a PC and the game hasn't had an upgrade so it's still 30fps
