Here are something people say about DMC2:
"Devil May Cry 2 sucks."

"The cameras are the worst in DMC2."

"Dante isn't really Dante in DMC2."

"DMC2 is a huge disappointment."

It's not just about the difficulty... I can easily beat (Normal) DMC1 within hours, (Of course, Must Die mode is harder. Much Harder. I had to retry for about an hour just to get a feel on the last encounter with Nelo Angelo. I have given up the Straight S plan on Must Die mode...)

Dante's personality has been changed, and his weapon, namely Ifirts, has been taken away, instead he is given swords. 3 different swords, but all of them have the same moves.

I didn't beat Dante Must Die mode on DMC2 though, because of some cheap bosses... the three heads thing. And some of the ultra-lengthy stages are tiresome as well.
