I would buy the game. Personally, I had NO problem with the camera angles or combat. Dodging was difficult to understand at the beginning but I quickly got used to it. Start the game on easy or medium, don't automatically go into it on hard and then complain that the game sucks just because you don't know how to use the controls.
I liked the story a lot and the music was probably one of my favourite parts.
I bought the game instead of renting and I don't mind.
I like to be able to share games with friends afterwards, but hey, thats just my opinion.
