I cant go anywhere without reading tons of hype and buzz for this game. Every outlet that has reviewed it seems to walk away crazy impressed. It seems the biggest surprises for reviewers was how much they would love the real time exploration and stealth mechanic, and how great, yet subtle the world building was.
Most seem to have not been expecting a lot from this game. Walking in expecting an average indie strategy with slightly above average graphics, and walked out lamenting that there simply wasn't more of the game.
So I am not sure which version of the internet you are looking at, but a quick google shows mew a lot of folk are over the moon for this title. And rightly so, it is way better than it has any right to be. Here is hoping the great feedback and praise result in good sales that entice the developer to produce some updates and DLC. Extra story, new characters, and perhaps some form of rebalanced New Game Plus would help this game's shelf life and replayability.
This one, albeit without the high Gamespot score to buoy at the time of the original post:

Don't get me wrong, I think an 8 is a great score, but anything less feels like it's being undersold (critically speaking). That all said, I love the game and am glad it's getting such great word of mouth.
