As a fan of the series since the beginning, you know, I'm fine with the improved gameplay and action. The series has almost always had action, but that's not the problem. The problem is that they seem to think that more action cannot coincide with excellent horror atmosphere. It can. It seems like they think that it's either action or horror. Why not have excellent action sequences and tighter gameplay, but mix it with creepy settings and horror-driven setpieces?
I don't think that many fans want the series to revert back to its slow, plodding and outdated gameplay, we just want that atmosphere back and I don't think that it's something that has to be excised in order to have more action and better gameplay. Revelations started out well and was pretty good for a couple of hours, and then the game just turned into a sloppy mess of repetitive action and uninteresting setpieces -- that's not the solution they should be aiming for.
