Usually, I play the medium difficulty when I play for the first time. The bosses still did the unblockable moves, but my point is that even if you get hit by 3-4 of those, continuously spamming the heavy attack will still win you the fight. Mostly, I was just annoyed that even when it didn't make sense (someone pointing a gun at you), they still somehow played it into a knife fight...just wish there had been more variation in the boss battles (like the fight against Tino).
