I just finshed Resident Evil 5 with a good friend of mine, Jeff. We would have been done with it much sooner, but work and stuff got in the way. Oh responsibility. The final boss was great. Very interactive and still fun. Overall I am pleased with the game overall. The controls are nice, graphics are great, and the voice acting is up to par. The AI still seems relatively simple, albeit you're combating zombies. Upgrading your arsenal is useful and fun and they finally got rid of that trench coat wearing guy that looks like he is about to flash you... Instead you can now purchase new weapons, but not ammo :'-( in between chapters, as well as First Aid sprays. After Resident Evil 4 they seemed to have given up on the "conserve the ammunes or you'll get eaten alive idea." Ammunition is plentiful (omitting magnum ammo). The story was great overall with plentiful plot twists and story shockers. At the end it doesn't leave you with the feeling that something is uncomplete. Rumors of Resident Evil 6 are already stirring about.
