Honestly, this game is so much better than 5, especially in terms of story and characters. Sure, the controls take some getting used to (especially swimming and some of the QTE stuff like climbing), but that's pretty much my only complaint.
I bought this game immediately, despite all the negative crap both the game and Capcom were getting. I've played through Leon's campaign in its entirety, and I loved every step. Can't wait to begin playing the other campaigns. SUCK IT, HATERS!
