All your fears have come true
Apart from the partner feature, it's not great to have nothing new to do in the new title, except for practically nothing at all. But if you consider the tiltle's unfeatured recycling feature, it's not much surprise.
The distribution of the action times and the quite times in the game is poor done. So are the start and the break of both.
Partner Feature: 9.5/10
The online coop-mode is simply one of the top awesome things you can ever do in a videogame.
A.I: 9/10
Some minor issues, like your partner could stand there shooting through you forever without trying to go around you. It is not though the big of an issue at all as it might sound.
Cutscenes: 9/10
Visuals: 9/10
Poor color filters for cutscenes. No good African style implementation in all game.
Minor bugs, like you could find your partner's shadow walking alone on the ground in front of you, while your partner is actually walking right above you on the corridor upstairs.
Music: 6/10
There's music, mostly that's is as far as you're gonna get. Totally tasteless. RE4 was a masterpiece in compare.
Sound: 8/10
Great for basic and mid-range details. Lacks for professional details.
Story 7/10
Most stoylines of video games are basically lame, but they present it as good as hell. The storyline in RE5 is a little very lame, and not much at all was done to manufacture that.
Summary:
If you're looking for a third person shooter, this is a 9/10 game for you. But if you are looking for a new Resident Evil title in African horror world, then all your fears have probably come true. RE4 kicked the hell outta European horror environment, but not RE5 at all. RE4 as well did an Awesome twist in may be all videogame concepts. but RE5 did just a relatively fair one, which is the partnership feature.
