I disliked Dishonored. Felt fundamentally flawed... Stealth games should build in a need to stealth, an incentive, a reward for stealthng-- Beyond stealth being its own reward. I just couldn't make myself sneak through the game because killing everyone head on was so excessively simple. So the game felt like kind of an average FPS with a bunch of stealth features that felt unnecessary, but you could do for the hell of it if you felt like it for some reason.
A good example of a great stealth game is alien isolation, where being discovered doesn't always mean death, but you really really don't want to be discovered.
