I get Mankind Divided, had the same feeling, but why Dishonored 2?
I think its too much the same game, and it has all the same issues as the first - a lacklustre story and characters most of all. They have some terrific writers at Arkane - you only have to read the books and diaries in-world to realise that - and all the potential is there for a ripping yarn yet they can't seem to make good on that promise. I can't say I'm sold on voiced protagonists either.
Also, as much as I like Karnaca its no Dunwall. In Dishonoured it felt like every mission told me something greater about the city itself. Other than The Dust District, I didn't get that same feeling from the sequel. Even The Dreadful Wale felt pretty lifeless in comparison to The Hound Pits Pub.
Having said that, my expectations were sky-high ...to the point of being unrealistic. I think it's good overall, great in places (level design) - just not quite the transcendent life-affirming experience I was hoping for.
