It isn't all Resident Evil 4s fault

[DerpSandwich]

Nothing is to blame but Capcom, and basically their greed. Anyone can take something good and try to recreate it and push it further and further into that same direction until it's junk, and that's not the fault of the original good work. Resident Evil 4 was purely good, and they weren't happy with just that, as basically no big publisher will be when they achieve something. It's their job to run with it until it's burned up.
