I've actually particularly enjoyed this one so far. The gameplay is a point of contention with some; RE has certainly stepped a good distance away from it's survival horror roots, but I'm in it for the story at this point, and the last game to legitimately scare me before the Dead Space franchise was the original Silent Hill, so I've stopped being disappointed by a lack of scares in horror games. Whatever your feelings on the gameplay, the controls are tight, and the addition of being able to aim while moving is a huge help.
The game does have both traditional zombies and the RE4/5 kind (the "zombies with guns" mentioned above, the J'avo.) The J'avo are a bit more challenging as enemies than the standard cannon fodder creatures of 4 and 5, with sharper AI and the ability to communicate with each other, as well as a much wider variety of dangerous mutations than the villagers of 4 or the Majini of 5. I've completed Chris's storyline, and though I can't say with certainly, my guess is that it's the heaviest on action; very much run and gun, a lot like RE5. I'm only one chapter into Leon's story, but I've found it to be a good deal creepier, with a larger focus on building tension than I felt in Chris's story.
The companions actually help in this one, as opposed to RE4's completely useless damsel in distress, and RE5's navigation challenged partner.
If you hated RE5, I wouldn't suggest purchasing this, but in my opinion, if you've ever been a fan of the franchise, it's at least worth a rental.
