You know, it is a little complicated.
The same way you might hate DmC in turn is how others might hate something you like and they probably react to it in the same manner as you or us have. In reality we might all be reacting in the same manner, the only difference been what we are defending and what we are attacking.
I'll tell you this, the only reason I've stuck with this series as long as I have is because of the original. Yeah, 3's got the combat and the characters and all the cuhrayzee in the world but it lacks that certain je ne sais quoi that the original had and none of the sequels did. It's not something I can explain but I have found something similar in other games so I don't complain as much as I did before I found those other games. Other disagree and so we argue. It's how it goes.
Now, if them crazies are all about "f#*k 2, 3, and 4" well, nothing you can do about it, let them enjoy what they will. You can't cure crazy with crazy, although, I kinda see their point.
