I found it to be awesome. The combat feels good, and it's the combat and the bloody takedowns that's gonna keep you going since the game itself is repetitive. The story is decent, but nothing incredible.
When I say "repetitive" I'm referring to the Assassin Creed kind of repetitive. You know what you have to do to beat the game from the beginning, and you're going to keep doing that thing until a story mission pops up and you get to do something more interesting.
Nevertheless, with all it's flaws I enjoyed it.
