Every fan? Is it right to speak for every fan?
While I wouldn't object to the old style being brought back, I thought RE4 was magnificient. As for part 5 my main issue was the story. Like you said the fight between Chris and Wesker...I dunno, im bittersweet about it, it was cool in it's own way, but something about the way it was delivered just left me wanting something else. I too would like some of the horror back. Part 4 was funner to play for me, because I felt that part 4 still had some creepiness to it. Re5 I can't really recall any really good gameplay moments worth mentioning.
Truth, I generalized too much. Well, I know that, like me, lots of them want it too.
