Unless the scope has been massively reduced, then its wrong. That certainly wasn't the case in 1 or 2.
Maybe the gameplay loop of beating the level, then trying to hit all the challenges wasn't for them.
PCGamer review says there are only 3 mission stories on most levels. Obviously, Hitman's replayability doesn't come from mission levels only but still a bit disappointing.
"In the other levels there are, surprisingly, only three Mission Stories per map, compared to an average of about ten in the previous two games' levels."
