It just bored me to tears, don't know what to tell you. I wasn't excited by the levels enough the first time to even get to Dante's sections which were just the same environments weren't they? It wasn't a fucking patch on 1 or 3 IMO.
That's because 4 was an excellent game, with a great combat system put to excellent use on excellently designed enemies, in some excellently designed areas.
Go to neogaf for many examples of the non converted. Baring in mind these people seem to hold 4 in high regard aswell.
