Arkham Origins had one of the best Bruce-Alfred dynamics that I've seen/read/played. The Joker introduction was actually quite good and the cast of characters was really interesting.
The fighting always felt off and I think it ended up suffering by being an incremental improvement over its predecessors without introducing much in the way of set pieces or features.
All of that being said, I'm not sure if it necessarily belongs here. It's considered to be the "worst" in a series of VERY good games.
