After having thoroughly played RE5, there are a lot of things to be said. Most of which others have already said.
Now, before anything, I must say I loved RE4. I still remember when I first heard that it would be in 3rd person view and you wouldn't actually be fighting zombies. I was so full of doubt, until I saw the first video of the village fight. After that, I was convinced it would be awesome. Lo, and behold, it was. Shitload of guns, massive inventory, plenty of things to shoot, and some of the most memorable bad guys ever. (Bitores Mendez anyone?) the only thin I disliked was Leons hair, it just made him look way to effeminate for my tastes.

Now fast forward to RE5, which is visually very pleasing, and gives a (somewhat) satisfying finish to RE's main bad guy.
Thees, unfortunately are the only real good points. Oh, also the Hydra shotgun, that is awesome.

The single most annoying aspect of the game for me is you partner's A.I.
It doesn't matter if you are playing as Chris or Sheva, they are both equally stupid.
This is nowhere more aparent then in the marshlands, where for some horrible reason, the developers thought it would be cool to add crocodiles.
Those mother fucking crocodiles.
Nothing in the entire game killed me as many times as those damn crocs, and all your partner will do, is run around in circles, most of the time getting in your way so you cant shoot the damn things. This is the part where I started to throw my controller at things and scream bloody murder.

It doesn't help, that you can only set the A.I. to cover, in which case it sticks to you like glue, routinely gets in your way, absolutely refuses to use anything other then the pistol until it has used every single handgun bullet in a five mile radius, and even then, only fires in short bursts with any automatic weapon.
The other option, Attack, just tells it to run around everywhere, shoot everything, grab everything, and completely ignore you, most of the time leading to some 15-30 seconds to get to the fucking "partner action door/gate/container/what-the-fuck-ever" which are even more elongated by it frequently stopping, making precisely 15° turn to the left, moving, stopping, 15° turn to the right, or just getting stuck behind a bloody wall.
This is what puzzles me most, the Majini A.I. is fairly competent at getting at you, so why is your partner considerably dumber then some insane parasite fucker? it makes no god damn sense.

Additionally this game is criminally short, its only 6 chapters, each with not much more then 3 levels. This wouldn't be so bad if some of the levels were longer, or in some cases, not so damn annoying.

Do I really need to mention how horribly stupid the inventory system is? Yes I do, and especially add that you partner will fucking pick up everything. it does not matter if neither of you are carrying pistols, it will pickup the god damn ammo, and force you to stop, tell it to give you the damn thing so you can throw it away.
This is a load of crap. Especially so when you have infinite ammo unlocked.

And finally, why the hell did they make Jill into a blond in skintight spandex? Its not like I don't like chicks in skintight spandex, I just don't want Jill to be one, as I generally like her.
