In summary its okay, get it on special and it will be worth it. Set your expectations and I think you will have a good time, in terms of expectations this is a run and gun with lots of gory action and some pretty fun combat so if that's what you judge it on you will have a good time in my opinion.
If you judge it based on its story and other aspects of the game I think you will be disappointed. I had the most fun just doing the side missions seeing how much credits I could make.
