I've said it before and I'll say it again, DMC 4 was a dissapointment.
You get half way through the game and then you're back tracking levels and bosses, I mean how lazy is that? Nero spends half the game yelling "Kirie!", which got old real fast. And I was one of the people who was hoping that once you beat the game, they'd do something like let you play as Trish or Lady like they did in DMC 3 where you got to play as Vergil, but no. All you get are harder and harder modes.
I'm not gonna lie, the game did some things right. The switching between Dante's modes on the fly was great, and the idea of Nero's sword needing to be revved up was pretty cool, along with the devil bringer and summoning Yamato, but after everything they did with DMC 3, DMC 4 just felt flat. That's just my opinion.
