All bosses were easy, imo. Game is very hard though, why don't you try it on difficult now?
And i think R2 is worth the money too, even if you don't like the campaign, online is so awesome.
Now why don't you try CoDWaW on veteran? After you play that and go back to R2, even superhuman will be piece of cake :P
