Combat is certanly not its strongest point, I wouldn't call it repetitive, I found it fun at best and serviceable at worst. The best part of the game for me was traversing Tokyo by night, the powers your character has make it very enjoyable and the landscape is beautifully crafted. Also there are a lot of Japan urban legends and folklore mixed in there too. I'd say it's a solid 20 hours experience. But it you are in it mostly for the combat I wouldn't recommend it to you.
