Almost there
City Watch guards care only about beating up people, whiskey and cigars, while overseer are half crazed zealots trying to kill anyone they perceive as heretic and thugs are bad as default. Weepers are worse, since they are zombie like creatures and the miraculous healing at the end by the hands of Piero and Sokolov is just a narrative twist.
Dishonored is not a stealth game, despite his branding as such, because Corvo, the main character, doesn`t mingle or try to blend in (taking the clothes and masks from a fallen overseer, for example), he`s just a showcase of skills and magic. The magnitude of his task requires contacts and a team capable to support, at least indirectly, all his exploits. Fall back places, a change in his demeanor or aspect and a dozens other tricks of trade.
I give this game 7.5 because the devs got a good story and an interesting steam punk universe, but let themselves painted in a corner and used all the cliches of the genre
