No, reviewers are complaining because the game is cheap, not for being difficult, there is a marked difference and if NG2 is more cheap than a challenge then it deserves to be docked points for it.
I'm still looking forward to playing it, but if the game resorts to being cheap in order to kill me, especially when NG shown that the game can kill you by being badass hard without cheating you, I will not be happy.
